4 x Warlock 1 x Priest, focus?

Been think of doing a PVP group for when I get bored of PVE..

So I figure I'll make (undead) holy priest and 4 warlocks.

I wonder how people set this up...

Usually a focus would be someone targetting the mobs, and it would make sense for this to be a warlock, but because I've got pets to heal it might mean more macros on the healer than normal - and so maybe is the healer was the focus, i wonder if there's an addon for healing - similar to what decursive does? to minimize the amount of macros i need.

Any thoughts? (i've used the search engine.. but there's so many threads it's hard to find if this has been discussed)

Try clique?

I run a 1x Priest (main) and 4x Warlock team, currently lvl24.

I am trying to keep my setup as simple as possible. I use Healbot on my main which removes the need of placing heal spells in my action bars for the Priest, freeing them all up for my Locks. Typical fight goes as follows...

Select mob with Priest, set all Locks to assist, send in Void Walkers, fire off my DOTs (Corruption & Curse of Agony... if mob is really tough, Ill throw in Immolate). After waiting a little bit for VWs to build aggro, Ill start wanding with locks... Priest stays idle for fast heal casts. If VWs start to get low, click on bars in Healbot and we're back in business.

On squishy mobs, ill skip the wands and move from target to target sending in VWs for aggro, DOTing then moving on.

I could probably add some damage spells from Priest to cast when I trigger a Lock DOT, but so far I havent found a need. Plus, I like having her readily available to cast heals on demand.

I hope that all made sense. Like I said, Im only lvl24 and still feel like Im discovering better, more efficient ways of fighting... so far the above is what works best in most scenarios.

I'd love some tips or advice if anyone has suggestions on how i could do better.

My 70s are set up with focus macros for assisting with DPS/targeting only. All the healing/decursing I do through Pitbull+Clique. Not a big deal in rapid-fire PVP because CoH > alliance, and if it isn't, having heal buttons wouldn't have mattered anyway.
