yes, probably, that's right, for the humans =_)
And can I play as elves? I just cleared the arena, and they gave me 10 reputation... By the way, the second hero here seems really tough; he defeats me before I can even take a turn. I mean, I could spend an hour and defeat him, but I'm afraid nothing will be left of my army.

I'll also tell you that there are 3 heroes on the arena for the orcs.
