I did exactly this with my first ever 60 and my housemate. I had a shaman that I played when he wasn't playing (he had a hunter for the same thing). Plan is basically destroy everything in your path including skull players or 2v7s until you hit 60. It's one of the easiest wow modes there is. Druid/warrior is so strong in vanilla that when they announced arenas for tbc I fully expected 2v2 to be all druid/warrior. Didn't think about the fact that the game might change a bit in other ways too 😛 You don't need anything out of prot to tank pre 60 dungeons unless you want to do them pretty underleveled. I played with it a bit anyway, but it slows you down far too much. This was before shield slam though, so maybe that helps. Spec arms so your levelling is less likely to be interrupted by other players (because you'll kill them), help your gf kite enemy players. You can duo elite quests 3-5 levels above you at some stages of your characters' development, so you don't need to stress about general questing stuff. The hardest it gets is basically from when you start hitting pvp zones until you get ww, your first instant attack using weapon damage, although it gets markedly easier again after you get pummel at 38. Mortal strike is good enough that I'd respec out of cruelty into mortal strike at 40 too, putting the next five points back into cruelty. One respec isn't too bad, only costs you 1 gold, although it does mean you're paying 50 quicker later on. I wouldn't suggest you level to 40 without cruelty though. My whole perception of this is likely influenced by the fact that I was an undead warrior and that we were playing on a server with much higher alliance population btw.
