5box grp for heroic farming?

[Chowdog]

Ok, I have a question on group comp for farming heroics daily.
In trying to minimize leveling time. Atm, I have 2 70 shamans(mix of heroic and pvp geared), 70 lock (fullT5++), 70 resto pvp druid.
Would these work together if I leveled a tank? It seems the overall fav is Pally on the forums from what I have read. I do have a 60 warrior that I haven't touched in like 2yrs. But a prot pally would make tanking easier with a non cc grp makeup like this.

I'm sure the lock will pull aggro over the other classes unless he has salv at all times.
So grp would be: 2x elem shaman, 1x lock, 1x resto druid & 1x prot pally (This would give great dps, ss for wipe recovery, druid b rez, totems, salv)

Or would it be better to bring up another shaman while leveling the pally?

It does seems like a priest would be best as they are my fav heroic healer when I run em with friends or guild

The 5 shaman thing sure looks fun but I can't see it working in all the heroics. My goal is to farm 30badges a day I doubt there are that many heroics that can be done with 5 shamans but I could be mistaken.

Either 5 shamans or Paladin Tank + Priest Healer + 3 dps.
