What is Training and how can you counter it?

Yes, they only limited the training for humans, up to 20 creatures I think, so high-level creatures will have to be transferred and there won't be a darkness of crossbowmen. Hurrah comrades! Hurrah Nival! Hurrah, patch 2.1!:D
And necromancers were screwed over too, so the Dungeon with its strong units, Sylvan with sworn enemies, and mages with magic will handle the human retraining

Rejoice, foes)))))), but our day will come too!!!! It's a fact that there won't be a one-way street; I think it will still be hard for you to compete with dwarves for a long time!!! Unless, of course, the devs hear your "kind" wishes again and release another patch for the "whining beggars" (no offense, nothing personal).
