Hmm I like that idea of using Mag as a atk stats since the main way damage is dealed in this game is mainly via normal atk..... especially with how they calculate skill damage.... 75% mag resistance is crazy.
Maybe they could just add it as a buff like berserker vincent's skill but it would have to be way more powerful to still justify bringing a mystic into any meatgrinder *ahem any legendary stage except gold mine.
Or maybe making your skill damage related to a significant % of monster Hp. Or else I do not see how doing 3k is going to be effective versus monsters with more then 90k hp.
Warlock and rune magus need even more work...
Warlock skill is too unreliable and could make it harder to kill your enemies and life steal is insignificant when most atk can almost OTK mystics.
Rune magus skill CD is way too high for it to be helpful in arena. By the time u get to use it, opponent already has a significant point advantage. The panels are also blocked by your own walls, so you also cannot get more points.
