Completely disappeared without a trace. And deserters, who should have been brought back from previous installments of Heroes.

No problem. I'm not trying to undermine the green faction. It's just about imagination. If there were also white units, who would that hurt? The more units there are, the more ideas there are, otherwise we'll soon be discussing everything on the forum and have topics like: Which is better, 15 assassins or 46 goblins, etc. We need to grow, develop our imagination, and firmly believe in the next expansion, which simply has to be released.
