Stop and think about this line for a minute. You've been playing since 2015, yet over a period of 4 years you're still ending up playing the game less and less. To me that means that voicing concerns doesn't really do much good. If the end result is still playing less, then at best you're probably just losing interest in the game after such a long time and at worst, you're fighting a losing battle with a company that doesn't really agree with your concerns and thus does nothing about them.
Or in other words...if you don't like it, quit playing. Most games don't change at all once they're released. Games that receive continuous updates tend to have this idea that players get to be involved in the development process since they're playing 'as it happens', or at least get to be more involved than they actually are. Expectation vs reality is a tough lesson for some to learn, apparently.
