The real issue here is the fact IMC doesn’t understand their own game strength. For some reason they decided to make ToS a Diablo/PoE like game instead of making it an MMO with focus on diversity (maybe because it was easier to manage?), which resulted in a game where you a giant range of options to pick from but you are forced into a specific path if you ever want to play the game.
Classes are slightly different remixes of each other, monsters are sandbags, weapons only matter to restrict your build and all equipment is under a strict power tier level. Whenever the game asks you to pick between X or Y you either have a clear right answer or is the choice only matters on the visual/cosmetic level. I will repeat this as many times as i need, ToS has no chance in becoming a relevant game until they focus on the natural path of their game - diversity.
On a side note, re:build didn’t killed classes and diversity (except for rainbow builds), the class design was never great to start with. The difference is that back then the monsters could threat and even kill you every now and then, there were significant death penalties and the power scaling wasn’t ridiculous, which made some of the flaws less noticeable. Re:build did addressed some important elements of class design and the class system but it never had the power to fix it all in one go, it was supposed to se the ground for future updates but there was no follow up at all.
