Going to have to say it's super character specific. Example, do that against doomsday, I'd love to see that. You'll probably eat his d1 for days. Now, if we did some testing on d1s or other quick lows it maybe perfectly reasonable.
I still have nightmares of some d1's.... like i dunno aquaman. Personally, after them blocking my d1 I'm sometimes lost as to where to go next.
Perhaps d1, d1, then trying to take a step back and b2.2
just spitballing, ima go start looking at characters d1s in training.
I seriously believe we need to test every idea someone brings forth, like you said in another thread we don't exactly have a pro harley helping us learn.
Edit: also with the remark about letting characters travel to you after a b3, i think you might be on to something, you can sacrifice damage for positioning theoretically....
