No dont listen to this nubs Go one colony in Hls. Makes it so your plunder from sos doesnt drop till 17th sos MAKES IT WAY EASIER TO CONVERT
Personally, because I osw, EE, and be an EB noob from time to time, I keep my attack buildings on the low lands. Easy to tear down and convert depending on the situation.
I used 2 CoE on my main, but with sufficient BFE it's really irrelevant TBH, i use bestiaries and do just fine on this account. (Not 300k for 3, it is 97.7k per Coe symmetrically)
I have one lvl 1 colony that i will eventually upgrade. I originally had the COE thing going but after reading Vals hansel guide i have seen the light right now my equipment allows me to hit ebs without pots
For a bank, titans lair. For warring... I would say t4 or 5 balanced, but really the building doesn't make much difference... It's all about BFA
2-3 attack buildings a tri - hansels with a t5 lvl 3 yeah someone will say you are an attack build lol
