I ran the group as a tank, 3 rets, and a holy before as well as five rets. This was back at level 20-30 or so. It seemed the tanks just worked so much easier and was faster due to not haveing to rez a team member after each battle. I have the 2-H heirloom weapon in each of the tanks bags already so it is no issue to swap some over to ret. My end game isn't to run tanks (crazy BTW due to lack of damage) but have a team of rets for face stomping fun in BGs/Arena.

For leveling I am still rolling through Wrath instances in about 18-25 minutes (Nexus, AN, UK) and getting good XPs so don't see a reason to change what is working smoothly with little to no deaths per run. I was just wondering when I would need to switch back to a standard trinity set up. I don't want to have to quest grind Cata if I can avoid it. I would rather BG/Instance grind. I did TBC heroics until almost 71 and they were as easy as the 68 level instances due to the stat increase at 70. I was hoping the 80 jump would be just as nice. I have a max level BS/Enchanter/Inscriptionist/Tailor/Alchemist for helping the team gear, enchants, glyph, etc... so I am leveling fast in a non-RAF way. I did optimize my macros/set-up a bit and will try to post them later to see if there is anyway to make it tighter DPS-efficiency and survivability wise.
