From your standpoint, I do not think you have a say on game development. Sure, SEMC is in a bad status right now but that does not mean you should put the final nail in the coffin. Game development is hard. Getting everything in schedule is harder. There will always be errors and delays.
As for the matchmaking, yes it sucks. But everyone deals with it eventually. It will also depend on your current rank and mmr.
I would stay off in stuff like “in t4 its normal blablaba” but really, you cannot win every game or have everything come your way. Learn to bounce back.
P.S: do you mean 2.9? because that is really a year ago.
