I would strongly look at click castsequences.

If you go with 4x Shaman + 1x Paladin, both classes can mash a single button, with the tank running through a "96969" rotation and the shammies casting their best spells in a priority sequence. This composition can run all heroic/challenging PvE content, and can run PvP fine.

Drive with the tank, shammies on auto follow. You'll have Divine Plea, as a manual click on the Paladin. And some assorted binds, to handle totems on the Shammies. Self Buffs and group buffs can be handles on the same number of keybinds as playing an all shaman team.

If you really don't want two class types, 5x Shaman will "solo" much more PvE content then 5x Warlocks. But 4x Shaman, with a "pug" tank, should be able to do most content. As far as PvP goes, 5x Shaman will be better then 4x.




The 5x Warlocks will do a lot of PvE content, but they won't go nearly as far in heroics as a team with a dedicated tank.

They have a lot of self healing ability. And with Health Funnel, can really heal their pet by a large amount.

However, their limiting factor is how fragile pets are, compared to a dedicated tanking class. That and relative threat levels. If you put out half decent dps on any of the warlocks, none of the pets will continue to hold threat.

Warlocks would be an amazing team for PvP, especially battlegrounds. Probably not so much in arena, unless you ran with a healer as well.

I'd strongly look at 4x Warlocks + 1x Disc Priest... Go with repeater region, click based, healing.

But not sure that you want to go with two classes here again.




If you want to run only one type of character, take a look at Druids.

You can spec them all the same way (Feral Cats or Moonkins), as far as leveling, questing, dailies and battlegrounds go.

With one spec'd and geared as a Bear and another spec'd and geared as a Tree (dual-specs possibly on these two), you'll be able to do all PvE content. Check out the assorted "Moo's videos" in the movie section.

I'd probably run 5x Balance, as that is what I'm doing on my druids now.
One is dual spec'd resto, and this is the only one with improved MotW.
One is dual spec'd feral, and this is the one with improved Faerie Fire in Balance.
The other three are a more generic balance spec.

They're a blast in battlegrounds, but lack a bit of controlled burst for arena beyond getting points each week.
