Then I played the beta.
Boy, was I wrong. First of all, the combat feels amazingly responsive. I feel like I'm actually destroying the abominations in real life with my lightning fast strikes. Combo system is very, very satisfying in that I sometimes don't even want to bother with spirit spenders. After I got the Fists of Thunder and Dashing Strike combination (which means level 2 in Beta), I enjoyed the game so much right from the beginning to the max level in beta. Rapidly moving all around the place (especially with the "Way of the Falling Star" skill rune for the dashing strike), jumping from one enemy to another. There is not one second to stop. And most importantly I play not for the loot, not for the extrinsic rewards, but for the gameplay itself, the feeling of the fight itself.
In the end, I'd like to send my apologies to the designers of the Monk. I was wrong, this class is so much fun and I'm happy to be proven wrong.
