I’m glad you are smart enough. Playing the game also since D1 Beta. I’m still having fun and don’t really see that many problems. But being critical without positivity and not to try to list solutions is not the right way.
What you think would be solutions to the listed problems. I would see for crucible matchmaking that if you play on let’s say the starter rank, that you only play with people from starter rank. If you reset your rank after max you play only with people who did the reset. And that you don’t play against four stacks or stacks as a solo. Personally I don’t encounter a full stack that often. But that would be a solution. Gambit needs some fine tuning for sure. As a solo player the Gambit is a bit easier and also easier to manage. With a team of four the game is harder because you play against four stacks and these days it’s tough, you see if a team of four summons the boss, the boss is sometimes down in 5 seconds. I’m not sure how to change that. And gambit needs to be somehow just one round. Like a new version of it or a 5 min round game.
