I returned to WoW about a month ago and two of my friends have also decided to resub. I am playing a paladin focused on tanking and one friend is a rogue and one is a mage. That means I both heal and tank. At first it was a bit daunting, but so far there really have not been any problems. Both of them plan on changing jobs @ 55+ but I really wanted to play paladin and we all wanted to play together so they are leveling these alts at the moment. The rogue has a 55+ priest and shaman; the mage has a 55+ priest and plans to be a deathknight. I tell you all that so I can ask...
How far can we continue to 3 man instances? So far we have done ragefire, wailing caverns, SFK and BFD. We have been able to do them at the top end of the "correct" levels too (SFK 24, BFD 26, etc..) which has been fun. Can we expect to 3 man our way through the old world? How about BC?
Best spec for 3 man? So far I took the 5 points in holy to prevent pushback since I'm healing myself in combat. Then I put the rest into retribution since, for now, it seems to offer as much as protection. I'll also mention I am willing to buy dual-spec (although I don't know how yet lol) so I don't mind if my 3 man spec sucks for leveling as I can create a second loadout.
I won't tell anyone what job to play, but as we discuss getting ready for high level dungeons we aren't sure what class combo will make the best group foundation. Both friends have priest, but I think the mage is very interested in DK. What comps Pld/Dk best, shaman or priest? Or who cares?
Also, we all like to PvP so if its ever apples and oranges, we would lean toward PvP.
