I dont have it myself yet. But based on the feedback ive seen from multiple content creators.
Mythoclast isnt the strongest option for anything atm (not that it'd stop me from using it).
...
I have a idea for a buff that would give it a place in the game without being so good that its broken.
Give its base auto rifle style fire overload rounds. Then give the linear fusion shots anti barrier.
...
Imo these two things would get it play time due to versatility without it being "too strong"

I suck but I was getting far more guardian kills than usual in PvP and Gambit with the Vex + cat. Seems fine. Yeah it's not the 3 tap it was in D1, but it works better than the version that was nerfed. IDK user experience may vary.
