I mean take it like this
This is fully charged (not a pve team just randomly slapped togheter and went to island to show)
This is 52k damage with retaliate which is the type of damage thats gonna work even for a good chunk of early UC
Slash all damage js generaly alot weaker around 10k wile fully charged so it works for a wile but its especily strong in stuff like game of hords and such thats not super buffed and she is gonna be stupid tanky wile hitting like this which is not something any other monster really can do
That is not taking her death revenge passive into account which as you know you can trigger yourself which is exstremly strong for pve already if you can set it up
But this last point is more for players like me who dislike the time consumption of pve and like to be fast about it and use heavy sweepers to just brute force insted of makeing sensible teams
