On the contrary pretty much any game that puts out content after launch has large changes to core mechanics in response to complaints. TC make plenty of mistakes and have some bad communication issues but lets not get hung up on what is pretty much standard for any ongoing game.
The gears community is split and TC are in a situation where they can’t win, they either listen to complaints and try to adjust things or they listen to people who are tired of changes and get complained at because they are ignoring feedback.
As for the game modes you seem to have missed my point, I agree there is a serious lack of variety that does not mean you should go and call what little there is “garbage” as the other poster did, that just divides the community.
