Swap Jab with Punch, making Jab the T2, then give Jab back Bruising and give it a non-stacking 4-second defense buff on a successful hit. This gives Jab a unique niche, where you willingly lower your own DPS to increase the team's overall DPS and your own survivability. The short-duration defense buff is long enough for you to use any other move in between refreshing the defense buff and resistance debuff, even Knockout Blow.
Super Strength is definitely on the devs radar, with changes a matter of when, not if. There's no doubt Jab will get something when that time comes, and I'd prefer this new wrinkle over a simple DPA increase.
