Lol. She has no strong or devastating builds in the campaign mode. Just a dysfunctional career skill that only really serves as an emergency thp source and a bunch of lackluster, directionless talents that don’t make any real difference whether you play with them or without them. The situation changes completely in expeditions, where she can potentially be the strongest career in the game. I think she could only benefit if some of that stuff was merged into the base kit in a more limited capacity. Things like exploding crits, or crits splitting into multiple projectiles for ranged attacks and so on.
A lot of stuff in the game is just too strong at the moment, specifically in the campaign mode (mostly elf things like moonfire bow, sword&dagger and so on) but there are also plenty of things that have fallen way behind the times and need attention. You can see the balance issues quite clearly in Cataclysm expeditions, where plenty of starting combos of careers and weapons will simply not get you anywhere, while some combos are so strong that you breeze through the adventure largely on the starting kit alone. Then the boons themselves are problematic, with plenty being filler material with next to no impact and a select few breaking the game largely by themselves.
All in all plenty of things would need addressing at both ends of the power spectrum.
