Overcompensating seems to definitely be doing the trick for now.
I just played about four rounds online on ranked just to try to get some of the timing down in actual matches. One was against a deceptively competent rank E Yosuke player, one was against a Chie who I barely lost, and the other two were wins over a Mitsuru who was still a bit too reliant on 5A and a Teddie player who still seemed pretty fresh. Shit, given my track record the last time I took Aigis online, this is definitely an improvement. But this goes more to my main complaint in ranked how you never really seem to get players at your skill level despite what the letter ranking says; only the match with Chie was pretty close, the one with Yosuke was a blow-out, and the ones with the others were mostly comfortable wins for me somehow.
Unfortunately, never really landed the Megido Combo because, and this relates to something that Marrshu mentioned, I had a bitch of a time trying to hitconfirm her 5AA into B under pressure. Most times I would either botch it or actually get that third A (which forces me to do the falling j.B combo, which is pretty hard to get in Orgia mode presently).
On another note, I am way too slow in connecting sweep to j.B in orgia. How fast does this have to be?
