Nations that seem strong/weak

LA Ermor

Typical for autospawn nations this is hard to gauge. I can't exactly say if Ermor is weak since i didn't play other LA nations yet to compare, however compared to D2 they took a few very hard hits.
Decent priests are quite hard to come by. No more battlefield undead buff spells for every army from turn 5 onward.
The autospawns are among the weakest troops for LA. The good national troops will wipe the floor with them, even without further boost spells.
Banish has been improved greatly.
Ermor is restricted to ashen empire, which is a lot weaker against indeps than ghost gate was because of a) not ethereal and b) no healing.
Ermor can't use a sleeping or imprisoned pretender.
Besides the pretender, the only magic paths are 3 death and up to two random picks on dusk elders. In LA whith standard settings (35% magic sites) every gem counts, and ermor needs to use a rainbow pretender to get some non-death mages summoned. At least in long games.

So, as i see it, ermors strength now lies in mid-game. Early expansion is slower than before and lategame all useful troops have to come from magic gems which are sparse in LA. after getting a few provinces set up with castles+temples and dom 10, and before the other nations have assembled big groups of LA troops with heavy protection and skills, ermor can still grab provinces with frighteningly large armies.

Conclusion: not terribly weak, but weaker than i'm used to. (well, i'm used to slaughtering my unsuspecting buddy with mass castings of ghost riders in games on really large maps )
