Consider trying to play say a hero like Logan. Kinda fun vs most elementals, rogue, hunter or warriors. Really fun vs against a Priest or Mage? No. Just a waste of time. Might as well concede asap. You can run through the heroes and, all but the tournament favourites who usually only have 1 bad match up, and the experience is the same. Rock Paper Scissors.
OP cards. It is hard to say what cards are OP because some simply are really harmful to one hero or the other.
