As I see it you have:

A healer
A CC/Dps (hunter)
A up and coming support/dpser (shad priest)

I’d say add a tank and a hard dpser, maybe a warlock. Sometimes its just nice to cut loose and make something go BOOM

I’d recommend leveling the warrior so that you can play any role for a group. Thats just me though.

I’d like to level a druid someday but I haven’t been able to find the time as of late.

If you are anything like me, you’ll probably enjoy tanking on a hybrid class. Warriors simply do not provide the flexibility that a druid or pally tank can. Therefore, you should make a pally tank.

Just last night I was playing on my 25 pally tank with a 25 rogue and 26 fire mage. We were doing quests in Raven Hill Cemetary in Duskwood when we saw Mor’ladim. He’s a level 30 elite, red to us. We decided to try and take him down, and we did! I held aggro and healed myself through his damaging blows while the rogue and mage whittled his green bar down to 0. A warrior could not have done that without a healer… I don’t even think a feral druid of the same level could have managed it either.

Make thee a tankadin!

Right now I have very little time to play, so I am focussing on alts because leveling is something that can be accomplished with short playtimes and solo (funny enough I had a few leveling companions). Currently I am focussing on the Shaman. I have a tanking option with my druid, a ranged DPS with the mage and I want to spec the Shaman for healing. It is also a choice of professions for me since the Shaman is leveling Jewelcrafting and Mining, the latter being the one gathering profession I have not yet at 375.

I am looking forward to having both a healer and a tank at the same time – I am not a big fan of respecs and I hope it will work out with the Shaman healing. I like feral tanking and neither Warrior nor Paladin looks like an option I would want to pursue for tanking.

I suggest going for the tank. Your warrior’s 40, correct? Arms is a decent leveling spec (it’s how I got up there). If you can get the gear, Fury works well too. It’s all about the gear, though, so be prepared to try to keep the best weapon you can get your hands on equipped. On the other hand, warriors can be a lot of fun. You understand the healing role well. Understanding the tanking role will (at least that’s my theory) help you become an even better healer. I’m doing a role-reversal with my best bud (who’s an amazing healer). He’s rolling a pally tank right now and I’ll be going resto with my druid. That way we can help each other out with the finer points of the jobs.

Having that flexibility is VERY nice. I’ve already seen it with my warrior and hunter. I was the only plate wearing tank for a bit in my guild, and we had a couple of new tanks coming up, so when they wanted to get their feet wet (and grab some upgrades) I was able to switch to my hunter and help with the DPS. Now, my guild’s short healers too often, so I’m hoping I can help with that.

The one problem I’ve seen with having multiple 70s is a lack of focus. But I like the variety too. I’d truly be torn right now if I had to pick one 70 to play full time. Good luck!
