There’s a difference between wanting a hero to be OP versus wanting to fix a completely broken hero. She probably is the worst hero even topping Salmon Loki (since its recent buff). She would do zero damage against a mono blue team, and isn’t even good against red due to the abundance of VF ailment blockers (particularly Grazul being a common HoTM).
Currently as she is, I find Jade to be a better and more useful hero lol as at least she mana cuts all enemies where as Exeera does nothing most of the time and at average speed. Compare her to other subpar heroes and she’s still excessively weaker/flawed.
But that’s just my opinion regardless of whether someone has her or not. These heroes have no place in the game IMO
