Neverending Flame Burst Combo

Potentially, this could be used on any monster, seeing that PINGing doesn't affect the stunning. How it's done is r5+ flame burst cancels flame burst after the 3rd(or 4th for r1) hit and it won't knock them back. Then, another player with r5+ flame burst has the time during the duration of the 3 or 4 hits of the skill to charge flame burst and execute it before the enemy could even move or charge a skill. Damage? Fails. Safe? Definitely.

Interesting, lol. It'd be kinda fun just to mess around that way, hehe.
