Lately, I've been playing on nothing short of MAX mode difficulty and best of 5 rounds. It's really satisfying to pull off a win in 5 rounds, especially if you are 2 rounds to zero down. It's an awesome feeling when you can turn the tables and make such a comeback. I use Kung Lao and ace the game on MAX difficulty and best of 5 rounds just about every time. Best of 5 rounds makes it more exciting, IMO, and I recommend anyone who hasn't tried it give it ago. Even if you are losing by two rounds, that DOESN'T mean your out, because in that time you can adjust your play and figure out a way to win.
