The hands is the least of my worries, the other changes are what seem like they might ruin most of the things this low-mid tear character has going for him. Even with that the hands change seems pointless, I'm guessing everybody out there who wanted to use Gen has already learned using the 5 inputs.
Both seem like they'll be useless. Chaining seems almost pointless unless it does more damage than mk. hands (I doubt), it becomes a matter of if it will allow him to get more damage off of jab punishment but he might not even get that. That's at the cost of his best way to get hits in close? Faster rolls mean shit given they don't go through fireballs, ex-rolls will still just be a poor mans ex-psychocrusher.
Needless to say as a Gen I don't see how taking a heavy hit to his offence (Especially against shotos, and Rog) and a severe hit to his defence isn't too bad. Especially if they still think it's perfectly reasonable to have Sagat keep two forward roundhouses into ultra.
