She is definitely with a insane DP a CC machine with reliable down smash.

And be naturaly tanky to all Magic classe. aka 90% of the player base.

Mystic is one (if not the most) "CC launcher" class of BDO. And as Catastigma says, is tanky specially vs magic.

BUT Mystic nowadays struggles in terms of DPS, is maybe to lower damage dealer of the game. 

That implies that in PVP, she must lengthen the combos to be able to kill which means that she must go to unprotected skills to achieve it. The latter also applies to the PVE being considered today by many a mediocre class to grind not because it does not have areas, but because of the time it takes to kill mobs in certain zones.

I've been playing Mystic for almost 3 years, I'm level 63 almost 64 right now. I love the way he plays, and mastering it is heartwarming.

I suppose that like all of them, it has its advantages and disadvantages

Class that takes a full 4 to 8 skill combo to kill after landing one of the worst range grabs being a God,  hardly...yeah no. If she hit half as hard as a Succ Wiz maybe, but the fact she lacks significant DPS keeps her fairly balanced.

The thing is, that classes in the game are not balanced around 1 v 1. Her job is not to kill, but to control others, and to especially shut down witch/wiz. The problem is the community, where 99% play the hard DPS classes and then wonder why PvP is so wacky.

I mean shes a tank support nothing wrong with that I kind of like it but losing her 100% succ skill was completely  not nessassary given nova has one that is not an ultimate and so does valk so why does mystic lose it???? Its just CC if your in it your in it its not like its wizzard meteor CCing you and then 100-0 ing you after breaking your block. Its CC
