Which creatures from the alternative upgrade options do you choose?

I made some new ones to see what they can do. I gathered more and attacked some tough neutral creatures. They killed all my skeletons, but then I raised them all back. That's why I respect them now.

I'm not saying they're weak. The new ones are better, but I value the Cloud of Death spell more than raising the dead, which the hero can do! Besides, I don't often play as Necromancers; I play as any race, mostly High Elves! So, Crystal Dragons, Wild Ents, Battle Unicorns, High Druids, Master Archers, Wind Dancers, Nymphs! These are my choices among the ELVES!:)
