I didn't just start playing fighting games a week ago, you know -_-
No I'm not a legit Yukiko yet. I'll admit I don't have a handle on all of the match ups yet; I'm still learning how to play defense and zoning, I've had literally 2 sessions online, and have yet to even fight some characters. But, the difference between me and random idiots is, I'm actually trying to do something other than: Dash/Air-Dash, Mash A + All Out Attack.
I CAN block mix-ups, I CAN memorize the order of blocking for Chie's Skull Cracker. The point is, when just about everyone I run into has a 0 connection, it makes it very difficult for me to play Yukiko as she is meant to be played. Reading opponenets, zoning, blocking mix-up, punishing, complex combos, and anything reactionary all go out the window whenever the actions on-screen follow nearly, if not, a full second after I make any inputs. Not to mention I think too much, and that's especially bad against someone who doesn't know what they're doing.
