I am among said people. While it is indeed true that unbalanced and buggy games are simply better with more player agency, I don't think anyone has said that the terrible premade Class System is the sole, or near-sole reason as to why the game is dying. But given the overwhelmingly negative response to the premade class system every time the issue is brought up, it's clear that premade classes are among the top 4 reasons as to why the game is dying, like we all said it would. Constant crasing, no custom servers, broken combat system, and premade classes would be the core reasons as to the decline. As to the statistical order of game-ruining they can be arranged in; nobody can say. My preferences *for why I don't want to play the game would be Broken Combat, Premade classes, with no custom servers and crashes being equal third.
The idea that someone like me that reviles the premade class system more than anything else in this game, is blaming the decline solely on this terrible class system, is a ridiculous strawman. I have yet to meet a single person that has said anything of the sort. And if they do exist, they're so small in number as to be completely irrelevant.
*edit
That's a reasonable response Sundeki and to be fair both yourself and Younes (and others) I will happily talk to because I'm more then willing to have an adult discussion about it. It just seems to me that there are bigger issues (like the crashing) that we could be talking about first.
