Hitting mechanic is actually great, it finally requires skill and timing. The ones complaining either simply miss the overpowered and easy hitting of just holding up on the stick or are unaware of the new mechanic.
My only gripe would be the slight underpowered outcome of the hits. Players recover from hits faster than 23 and injuries are not only less frequent but short duration when they do occur. If hitting is going to be as challenging as it is(which i do enjoy) please up the reward for being a skilled hitter. More winded get ups and stamina drain at the very least.
I think hip check logic needs to be toned down. Currently small players bump the BACK of a power forwards knee and send him flying.
