I had that problem when I first started doing PvP. You just have to figure out which moves have the most super armor and super armor break. Like for my merc, rising slash seems to have a decent amount of super armor during the first 2 parts of it, but when I jump in the air for the third part I'm vulnerable as hell. Stomp has low super armor for the first half second its casting and a decent amount during the actual stomp. For a lot of moves, it seems like the first half second of the skill has pretty low super armor (probably because of latency) and then it gets a lot more. The exception for me seems to be flying swing where the super armor is pretty much instant. I've actually taken advantage of this and used flying swing to tank boss moves I can't avoid. A skill that seems similar (but in the opposite way) is tumbling shot. It has instant invincibility frames.
That isn't to say that you don't get BS'd sometimes, but that's probably latency.
edit - OMG YES!!! OMG WOOOO. happy right now. Just made a +11 lvl40 gauntlet like I wanted
. I used the 5k NX I got from the e-mail to jelly my gauntlet after +10. That's my first +11 enhancement.
