I genuinely have no clue how succession musa is allowed to exist in its current state. Compared to other classes it's like it's from a completely different game. The class actually has enough damage on equal/LESSER gear to kill people from 100%-0% in the duration of the shortest CC in the game. Watching someone die from a singular skill just because they got stiffened is worse than any other balancing mistakes PA has made in the past (maegu, drak, DK release). Whatever reason succ Musa players use to justify that level of damage is absolute nonsense, as if other classes in the game don't have to play around having little protection/etc. 

U just perfectly described Musa. It,s a glass cannon. Without any real cc he is forced to blitz in , burst-dmg, blitz out. In some cases he'll one shot u, in others he'll insta die . That's all he left, some burst dmg. If u think u can mindlessly chase around...if u just think about it u are already out of stamina. It's an ambush class! Burst mobility, burst dmg. Thats all. No grab, no real block, no cc, just pure dmg. He cant even fight Aw'Musa face to face, 0 chance against the real big boys u mentioned. I highly recommend trying these classes out before crying about them.
