Just got told how easy it is to counter by unsympathetic people in Chat and how I should have used my own stun, even though I wouldn't have had the time or opportunity as I was in fact stun locked the entire time.
There is always a core of people like that around any game. They are generally assholish types. I've seen it time and time again.
At any rate, I can't comment much on your foul grasp question, as I don't know much about it. But I can say that I did get stun-locked by a TB the other day in ice mode. Like, continuously. Like, no opportunity to break out of it or do anything about it.
