Making Jaguars home-only and eagles recruitable everywhere would be a big nerf to MA Mictlan. I dont think MA Mictlan needs a nerf.
Mictlan's PD is also awful enough already, eagle warriors wont help it.
Btw, speaking of nerfs, why making High Seraphs home-only? Its not like Caelum is as powerful as its used to be in Dom2. Lightings nerfed, quickness nerfed, false horrors nerfed, armies bigger than in Dom2 (so harder to overshoot with combat spells), High Seraphs old... Arent you affraid it will be the last nail in a coffin?
