Vanilla warrior here and I must admit, it's not as bad as it used to.
I haven't played pve with my warrior in years so I'm mainly talking about pvp and back then, disc priest were a nightmare because they kept you rage starved.
But at least in pvp, I still feel like half of the time I spend waiting on my attack to give me some rage so I can do something.
Or, you are constantly attacked and swim in rage, but then you either die quickly or the enemy notices you have a healer and changes the target.
Maybe I'm doing something wrong being rage starved almost all the time, but it feels boring compared to my shadow priest who always has something to cast.
I was hoping there would be some change to it after all these years. It's disappointing to see not much has changed.
