I think I know what string you're talking about: WS + 4, 4, 1. I normally use just WS + 4 because it's safe on block and plus on hit. But, I like to mix it up and test the waters to see if I can get away with the whole string; the last hit is delayable.
Yeah, the lag was funny last night. For the most part I had no problem. But there were these 1-3 second spikes where the game completely slowed down out of nowhere. I live in Mexico, so I understand if the connection is shitty sometimes.
P.S.: I did abuse throws during the last matches.
