Lol dude, I've used overhead in CS1 like below 10 times in a year(i wasn't used to RCing that time so i never used it due to -16)
The overhead buff was a like blessing to me, It reminded me "you got a fucking ground overhead, USE IT". I didn't mind the need to RC since i couldn't even do midscreen overhead combos without RC (sekkajin pushing them too far cause i forget to do dash with 6a)
And yeah I've seen your post about hitting a wall in terms of improvement. I'm in the same boat, got annoyed and slacked.
Funny how people say i've improved a ton even though i haven't practiced for a month lol. Probably lost some bad habits due to slacking and forgetting them.
