Ive been talking bout this issue for ages. That a group of players with grab classes can bully someone infinitely like this one without letting the grabbed character die. Or used to hunt down whales, by chain-grab-locking them and bombarded with skills from a teammate, regrabbed by the same teammate and your turn to cast heavy skills.

Can easily annoy someone in Black Sun. And yes we've tried it way back before the Black Sun was moved to the Great Desert. Wait someone to pass by by hiding behind something and start an infinite grab.

The point is, it is a fun mechanic, but it only prove the game's lack of class balance even way back then, because classes without grapples can't do so. 

PA really needs to update the CC mechanic. Apply full immunity CC after the last CC landed. Or patch the CC mechanic from PC ver. to mobile.
