I’ve watched a lot of Avexys’s vids and have always enjoyed his content. While I certainly don’t play anywhere as well as he does, I’ve learned a lot of tips and pointers and have gotten better from his insights into the games.
I’m glad a top pro is saying what the community here on the forums has been saying. That the new tuning is too slow. On top of being too slow, TC added in shot delays that punish you for outplaying your opponent. We’ve all been there, where you make a nice move and are ready to chunk your opponent, except oops, no. Shot delay. You’re dead. The Op4 tuning was good and I feel like a lot of people on the forum felt the same.
Some of the other things he said, I’m not sure I can sympathize with too much. He’s kind of complaining that basically unknown. ranked players can sometimes kill him. I mean, cmon. I’ve watched plenty of his videos and the guy dominates almost everyone in this game. He said in previous Gears games , at times he felt almost unkillable. That not a reasonable expectation, IMO.
He said something else to the effect that sometimes ranked players can kill him because they do things or make moves that are unorthodox or unexpected . Hard to sympathize with that one. Sometimes you get a kill on a really good player because you make a move that is unexpected or unorthodox or maybe just because your’ not a pro and don’t play like one.
In any event , it’s nice to hear a top pro complain about some of the same things we do, even if he’s coming from a different viewpoint than most of us. He thinks it’s too easy for casuals to get kills on him. 
Now that one of the kings of Gears is saying what us mortals have been saying, perhaps TC will take notice.
