For people complaining about the grabs, please do remember that this stuff isn't final. Tyler said they are still tweaking Commando stuff as well.
But I feel like the choice of range was to stop another Bane-train. Having a quarter-life unblockable armoured grab with crazy reach would probably be too much considering how quickly you can close a space gap between non-zoner characters, and the fact that he has a pretty good projectile in knives that will definitely annoy a lot of characters. Remember that in Injustice, you essentially dealt a half of the actual damage because of how the round system worked, but we're back to 100% damage rounds in MKX and guessing wrong twice against Commando Kano means 50% unbreakable damage.
