Yeah, you totally can. But buffering the armor between the gaps is kind of a dangerous game when both 11 and 111 are safe. If we decide not to pull the trigger on our full string, a buffering opponent is full combo punished. That'd make me think twice about buffering. I personally don't respect my opponents options until they earn it. That's where I'm coming from when I say guessing.
As for +2, I've seen CSZ players stuff opponents on the regular after a +2, especially at the range 114 leaves him on block. 111 starts up in 6f, meaning nothing but armor is touching CSZ. Unless they low poke, right? But then b2 and NJP catch them. And those lead into some of the most ambiguous set-ups he's got, leading to ~50%. It's another guess, where the opponent hits with a 2% low poke or lose half their life bar.
There's no wrong way to look at this, either. I'm just sharing what works for me, just suggesting applying 114 sometimes.
