I would like to see some kind of bird for the Elves, or some cool monster that would please me (but I really don't want them to remove the dragons).
I would like to see more variety from them, but not animals, but Elven units (if they even exist).
Oh! They could give them a tank. I remember in Heroes 5, it was on one of the maps. That would be fun, an Elf in a tank:D (It's nonsense, of course, but don't kick me too hard).
