Lord Thane
I think the small training bump for orcs castle training would be beneficial, though I would probably limit it to 2 TC/ATC per castle myself.
I like that change to undead, both thematically and mechanically. Though I would make it so legion aren't in that calculation, because that just makes no sense lol.
For Elf, keeper once mentioned raising the floor stats of caragous and lowering their ceiling, but Nolio had once suggested maybe making their floating stat calculation work like shieldbearers, in that their strength is determined by how much of a percentage of their own army they are instead of the opponents.
I think that's a good idea, especially given you now have 2 races (undead and gnome, could argue orc as well) that can render them useless in their current state quickly with fast training fodder armies. And caragous train so slowly and are expensive as all hell. (I will beat this horse well past its death)
