Keal gets countered by any diving melee hero. Anub, Muradin, Illidan and so on. In low level games his chain bomb just wrecks face because uncoordinated teams just spread it like cancer
Considering I have no idea what that is, I'm one of those people!
Just won a match where I didn't get any exp or gold, but it did count towards my quests. Does that just... happen sometimes? I could only view the talents/score screens at the post-game, not the exp summary.
