Tip for the ones that are having trouble on mission 4 on easy mode: Just use archers (they don't need to be strong ones, but they need to be archers, not mages, not fighters, not warrior). Then after making 8 archers, don't try to rush the "destruction". Just wait. After u first hit the giant black fighter guy, wait till he gets close to your champion (make sure u evolved ur champion mana regen) and use the arrow rain skill. It will push him off. Wait till he comes closer again, use the arrow rain and use the rage skill. Keep doin' it 'till he's dead. + if this helped ya.
You should let us make more than 3 characters, that sux to have to delete one in order to make the same character in another mode. Or instead, we should be able to get a character and move it to another mode (Like, making my first character ever be in supermob mode, for example)
