I mean, there are turns where you pretty much HAVE to play your overload cards and then you just sit there crippled horribly your next turn and instantly go way back behind.
They need more ways to remove overload. Maybe a minion that does it as well. Lava burst is okay in the right deck but a tempo minion would be insanely better maybe with the overload reset equal to the number of overload minions in play or something.
