Very interesting arguments. However Gath is very strong as is and getting stronger every turn. Led by an expert player that I respect based on bitter experience it is currently #1 in power balance.
True, I wish to change that for my own selfish reasons
If I fail to act now then it's game over - Gath wins. So, more or less, this conflict is mandatory.
Now, don't forget that chaff doesn't win games. It's gems and research that do. So 600 undead are nothing compared to mind hunts, or RoS, or SCs etc. Ermor is way behind on research so it may look scary but it's true offensive power is severely limited. Had I been in Gaths position I estimate that I'd have killed Van and then Ermor w/o real difficulty.
Hey, if enough players want it I could consider keeping the NAP with Gath and just let him win
