Next step to PvE.

Heyas folks.

Well after getting atleast a few items for my 4 x shammies from PvP I decided it is time to start PvE'ing as well (also PvP gets tedious after a few weeks). However I started to think what I should use for PvE'ing and came to the conclusion that Holy Priest + 4 x Shammies could be nice and that it was/is.
I played before with my feral tank but the problem always seemed to be the over agroing from my shammies which started a huge confusion (not always but enough times), now with the priest though I have the control of always getting off good heals while the shammies can do their dps thing.

I would ask though for some tactics or ideas that I could benifit from in the future instance crawls, especially when starting HC, as I feel there is so much more I am missing out.
The good thing is my priest and feral tank are on the same account so switching between these two is not hard.

I cleared SL and Mech normal this evening without too much problems (after a few wipes on Murmur until I recalled that a Ele pet was needed :P ) and almost feel brave enough to go and give HC's a go.

Any thoughts or feedback would be greatly appriciated.

Thx.
