I was a Grandmaster Sombra who retired after they reworked her.
Basically the changes are
-5v5 instead of 6v6
-Assault maps (Hanamura, Volskaya Industries, etc.) are no longer in competitive mode.
-New gamemode that I forget what it calls but it sucks.
-New heroes that come out are busted until the next one comes out, then the not-as-new hero is nerfed.
-Microtransactions up the ass.
Needless to say, I have had no desire to go back since the most fun I had was playing as Sombra, and I can't have that fun anymore.
