I really don't see where people are coming from when they say the nerf is bad for the game.
It pretty much kills the need to use anything else in almost all endgame content. With and without breach and clear.
I'd be perfectly content to see it removed from the game, just so I could use other exotic weapons without actively handicapping myself. Nevermind a nerf that'll keep it viable in endgame content, just not completely dominant.

The weapon will still be good. Pve will still be easy. People are just crying to cry.
