It sucks for the ones who just want to play the game as "intended". The min-maxers always ruin it for everyone else. The devs ultimately balance the game around the few percent who min-max and everyone else just has to deal with it or stop playing. And the they say "don't blame the players, blame the game" but the game is literally being warped because of the players.

Also, often the new meta doesn't even make sense and the changes need to be rolled back. So all that pain and hustle will often be for nothing, but a lot of players will end up having a bad taste of the game altogether. So the damage has been done and a roll back can't fix it.
