Their both unsafe on power shield.?
Darky is saying there's some risk but it's worth the reward. And yes, bair is safe, not 100% safe but you have to hit ICs eventually and bair is the safest move.
Edit: P3, he's saying the 1-2 as in the hitboxes
Bair is only safe when spaced perfectly. And if you miss, hit nana or hit teh power shield, the RB isnt safe.
And I doubt bair beeing safe even when spaced perfectly, but I'll give ya that.
