I just hope that anything in the future is linked to worthwhile challenges over meaningless grinding of low level stuff to increase your ilevel to the max, which is confusing. We went from fun/challenging boss fights to face rolling trash mobs.
Also to your point, the feeling you are going through right now has happened to quite a few of us multiple times over the last couple years, it's disheartening and I hope they really fix the overall system.
Maybe with them finally getting ahead of the game, they can do more on oversight.
An old Example is Savage Blade and Skull sunder being pld/war cross class. never would you use them, but then keen flurry is lancer and yea we dont get to play with that misplaced skill.
