All fighting games are notorious for bad netcode. But MK has the worst, i heard street fighter is somewhat playable most of the time. MK9 is downright impossible 99% of the time.
That's dumb. That's a less exaggerated version of "Well at least they only raped you once, Timmy over there lost count!" We're still being taken advantage of and ruined by something another series (ahem SCV) has perfected to almost that of an art form.
My main irk with online is that regardless of if your stricter combos will land, you still cannot AA worth dick. The inability to AA is the one major flaw to online. You can do it on anticipation but no way can you do it on reaction.
