Same here. I would not say "never", but this transition spamming keeps you from punching. I see the same problems in side-saddle and crucifix. Yes holding my opponent there all day long is not the problem. But doing something meaningful is.
So lately I try to submit them, if I see that they just spam transitions over and over in that positions. It works usually well, since they have no stamina left. But its somehow not really satisfying and feels like a cheap win.
