Yeah, it seems that Mictlan would give the Usurpers team more flavour than R'lyeh. R'lyeh is designed as water nation and should be played as water nation. Actually all of their troops are quite crappy and not cost-effective with one exception - the Crab Hybrid which is aquatic but helps underwater expansion a lot. (Some people may say that Shambler Thralls are cool but even though they may be cool there're always better recruits. Not a matter of discussion now, anyway)
As a balance adherent, I'd rather see Mictlan in the Usurpers team but of course it is not me who decides, so it's just an opinion.
p.s. Actually I just can't wait for a fight and I'm willing to face whoever and whatever if that makes the game start sooner
