Depends really. If you take a look at his other options from 1,1. Those being 1,1,3 and 1,1~SD, they can't be interrupted. Mixing these up with 1,1,2 would make it extremely hard to react toeven if you "jail" them on a ji2/3, 11(2<< can still be B3mb). It is not worth eating a 35% combo for +++ frames. Unless they have no meter.
To my knowledge there's no absolute guard system in the game where you will be held in blockstun regardless of what you are doing. If someone's trying to press buttons after 1,1 then he has options to blow them up. Maybe there's a way to get around the followups but I'm unaware of them
IMO the + frames are way too good to pass up, it wouldn't hurt to add 1,1,2 to your arsenal
