I decided to compile some popular dome placements for the original 30 planet layouts. It seems the links for the ones on the first page are broken, and they're out of date anyway.
NOTE: These are just popular
placements, not necessarily in any order of difficulty. I've provided some commentary on how I feel personally about each dome-spot.
This layout became more valuable after the SM patch because it's difficult to SM. Spot #2 is probably your best, safest bet. It's a PITA even with a weak solar. Location #1 is nearly impossible to cap with a wide, 120-burst solar but it's more risky.
This layout is pretty weak no matter how you look at it. If you're going to dome this, you gotta put it in this spot so that the cap run isn't so easy. It's also not all that easy to shoot nukes into that room either if the military is way up.
This layout used to be very popular, but now is very easy to invade with surface missiles. Avoid it if you can, but if you must dome it, put it in spots 2 or 3. Spot #1 is popular but not very good.
#4 (little hard to see, sorry)
This layout has many possible locations. I've tried to list them in order of popularity (spot #1 most popular, #5 least popular). I feel that location #1 is still the best, but #3 can be good if it's defended well with a high-BPM solar
I was going to list all the popular spots, but I decided to mark the ONLY spots worth doming. This spot is 10x better than anywhere else I've seen on this planet... and I've seen some baaaad spots on this one more than other layouts. Please, if you're going to dome this planet, dome in one of those two spots. I like #2 better, but you can't go wrong with either.
With the introduction of mods, this layout is not as good as it used to be. Spot #1 is the most popular; Spot #2 is just as good if not better.
This layout also kinda sucks now. If you're doming a rocky, feel free to put it where I've marked. If it's not a rocky, don't dome it. You're just going to end up with the sh1tiest noob-ring you could ever imagine.
This layout always has, and always will be fairly easy to invade but not a cakewalk. I would recommend spot #1 over #2, but there's not a huge difference.
Everyone seems to dome this layout at spot #2, but DONT - such an easy invade. Spot #1 is better, but not by a long-shot.
Most people dome this layout at location #1, but that was before surface missiles. with the new mods, #2 is the better choice because of solar coverage.
I see this planet domed terribly quite often. I can't truly decide which one of these two possible locations I marked is better. they're both moderate to invade - not super tough, but not easy either.
This layout has some nice nuke-eater spots. I highlighted my two favorite. I've invaded planets in those spots hundreds of times. You can't really go wrong with either spot I marked.
The best (and most common) spot on this layout is spot #1. It's still not too tough to invade, it's just expensive and irritating. #3 ain't too shabby if you want to mix it up. I put #2 on there because it's popular, but it really sucks compared to 1 and 3.
Spot #1 is the most popular and was the best before surface missiles. I'd argue that #3 is better, now. The first spot is very prone to team-invading because it's easy to distract the solar at warp. It's not too hard to have one person distract the solar while the other SM's out the whole colony without using any nukes. #2 is not as easy to invade as #1, but #3 is better IMHO.
This was always a favorite of mine. I sought this out on rebangs before the permas, and I still seek them out in rebangs and extended rebangs now. It's not as tough with the mods as it used to be, but a rocky colony domed at loc #2 is still hard to handle. #1 is on there because it's still a popular spot (but weaker). I put it on there because I want to keep newbs doming there so I can practice my domeslides
..... #3 is decent if you want to be different.
The sperm layout has always been a builder favorite - just don't screw up the dome placement.
Don't be like everyone else and stick it in the terrible spot #1. Sure, you can put trip-lasers in the middle arm, but it's still super easy to take. If you want to put the dome near the warp, try spot #2. If you want them to have to work a little bit harder than drop-nuking, use spot #3.
Meh, I hate this layout. Spot #1 seems to work out OK if you need to dome this layout and it's a rocky planet type. I've seen many folks try spot #3 but it's meh.
#19 - The Worm-Tail
This layout is coveted on the older permaverses that lack the new layouts. It pains me when it's domed badly. Put the dome at spot #1. It's nasty, just nasty. Spots #2 and #3 are very hard invade, but they're both easier to take than spot #1
This is an easy layout to invade no matter where you dome it. However, I highlighted the three most popular spots.
#21 - The Super-Wide
This layout can kill a hapless newb that happens to land when the Lauch Zone is lasered, but any vet knows that the lasers can't reach the very bottom. I say put the dome at #1 if it's a rocky/arctic and #2 if it's any other type. #3 is a popular spot, but it's very weak to a good invader.
None of these spots are particularly easy to invade, but I feel spots #4 and #2 are the hardest out of the popular spots I marked.
Dome location #1 works out OK for this layout. I don't know why people go for spot #2, but they always do - so it's on there, too.
There used to be a lot of decent spots on this layout. Now that surface missiles are prevalent, your best bet is to go with this spot and laser the warp with most lasers concentrated around the right side the warp - make sure to put plenty of lasers below the dome.
There are a lot of folks that think it's cute to dome this layout somewhere in the middle where all the spots are. Dome this layout where it belongs in one of the spots I marked. It's 5x better than anywhere else you could put it on this layout.
I've seen this domed in the bottom-right bubble (which is a terrible idea). Dome this layout where I've marked. It's not very fun to invade.
One of the twin layouts. Put the dome where I marked.
This layout is pretty versatile. You can dome it many good spots. My two favorite are marked. #1 is the safest spot, but #2 is annoying as heck because of the trip-lasers that can be placed on the other-side of the top wall. Very tough to nuke. You either have to go around and attack from the rear (har har) or ram-nuke the lasers from the front. Personally, I dome this layout at #3. It's a PITA to invade.
Dome-loc #1 is is surprisingly effective. #2 remains strangely popular despite it's inherent weakness to SM.
