Honestly I’ve been switching between prot and fury and I don’t find prot to be any easier. Really the only thing I need it for is for is the pack before rexxar, and maybe that first hallway if you go to the right wing (only because it’s real easy to pull an extra pack). But I’m told you can skip the pack before rexxar (I personally haven’t made that skip work).
Maybe warrior is exception because of how amazing impending victory is when there’s lots of mobs. I don’t feel squishy at all as fury. Maybe I’m over-geared, IDK.
Edit: overall I think the “hard” parts are pretty class specific. The pack before rexxar is pretty easy on my mage, but rexxar is a nightmare. And rexxar is pretty easy on my warrior… if I can just get to him lol.
