Depends on how big the change is and how other people react, because of how very slowly the Invective regens ammo I don't see that as being a huge problem, but the Ice Breaker is another story altogether, that thing regens ammo so fast that anyone sniping with it will never need to worry about running out of ammo. If people start using Ice Breaker en masse then I probably will too just to compete, but there's also a pretty good chance I'll just stick with my current load out (Timur's Lash, Felwinter's Lie, Jolder's Hammer). If they really nerf special ammo hard though may also consider using Universal Remote, especially if lots of other people start doing so I may have to just to keep up.
