unfortunately that is the case alot of the time due to the limited functionality of what a warrior can do for his teammates outside of disarm/intervene/demo/tclap/ charge/intercept stun . At least as a prot warrior you can be looking how your parties health is in regards to spell reflecting/using the safeguard portion of intervene etc
It is still worth it to keep an eye on your teammates bars tho so I just have them in a more out of the way spot on my screen.
Yeah, I will agree that prot has a higher skillcap than arms for the reasons you stated. That is why i am having so much fun with it. Rather than facerollling my rotation like I have for the last 3 seasons, I get to try new things, make mistakes, and learn stuff.
Higher skillcap = more fun.
Keep in mind though, becuase of prot's nature, its higher skillcap also comes with a "more forgiving" to mistakes clause. You can miss a bash with prot and still do fine. But if you are able to coordinate well, prot can become unstoppable.
