They simply would not put solar burn on the nightfalls. Daily heroics are already a joke. Crota is cheesed constantly, so no real argument there. Besides, unless you're rolling solo, a group can easily take down crotas shield. I would rather not see it nerfed, but we all acknowledge that it's OP, and it most likely will get a nerf eventually anyway. You can easily take Atheon down in 2 teleports without any ghorns as well, so I'm not sure about that Vault comment. Wether xur sells it or not, more people will be getting the weapon as time goes on, so I don't think it matters much. Every weapon is situational. I'm sure plenty of people run other exotics up until the bosses, and then switch over, because nothing else has enough health for it to be effective. If anything, I see icebreaker getting a nerf. Constant ammo recharge, max range, high impact sniper rifle, useful in every single situation.
