It’s funny because the way everyone is going on about her she sounds like a “cheat mode” character that you give to a young child relative to play a game because they’re not very good.
I currently can only go by the descriptions everyone has given about her gameplay about all the apparently devastating effects because I’ve not got her unlocked and despite playing a large number of PvP games every day since she’s been unlocked I’ve not faced a single match up where she’s been involved.
This is hardly surprising as I rarely match up with anyone who even has Joppa or Jarlaxle in their team and have only faced Pikel about twice. So people mustn’t have them sufficiently levelled up.
I’m guessing due to the rareness the average player has of facing Coriolis it can’t exactly be considered to break the entire game - more an annoyance. Perhaps those higher up face her more often and as more people unlock her the complaints will come flying in and they will be forced to balance her.
I think it’s impossible to compare a showdown PvP instance in this game to actual D&D balancing because in a real D&D game you’d have potions, summoning and the environment to use to your advantage - none of those are available in this game.
So hypothetically someone would cast a squad of skeletons as a distraction to Coriolis whilst getting their Rogue to drink a potion of magic resistance and then going stealth and sneaking to perform a backstab. Or a myriad of other creative ways.
