Sigh... Goo, but you aren't the only one to post this
Look, I just visited a few other people's threads, and your thread is probably better than theirs. But, like I said to them, some of the heroes proposed stink. For varying reasons.
1.) the Wizard Lord would be insanely OP. By my calculations when comparing it to a Barb King, it would have 2380 health and about 568 damage per second at level 1. Imagine that, at level 40, with rage spells and the other heroes. All by itself, it could annihilate a TH 10 in under 5 seconds. Plus, it would have ranged attacks.
2.) The goblin king is a stupid idea. Basically, it would be a barb king with less than 1/2 the health, double speed, and about 10 less damage. Why not just use 100 or so regular gobs and upgrade them? That would actually have more total health and damage than the Gob King.
The Ogre, though, is not a bad idea. Maybe, for its special ability, it could stomp on the ground and make an earthquake or something.
