I'm giving Blizz the benefit of the doubt here, they said they want to use PTR to test more zany things out, and obviously you don't shake the whole damn thing up otherwise you'll never get good data, so I'm not upset they didn't put the Sym changes or change anyone else.
These particularly changes look purely numerical rather than functions. "Would Soldier lose the 'poor man's McCree' title if we buff his damage?"
