I rock:
Main group Warrior, Cleric, Ench, Bard, Necro, Beast - a little overkill with the utility, but I enjoy this group.
Shitter f2p diamond group - SK, Clr, Ench, Wiz, Wiz, Mage
I meant to add: The point of my reply is that while my main group is not an intense crazy dps group, I am very sturdy, and it suits my necro being able to ramp up and then pull another mob with constant mobs and no downtime
I find that a SK/Warrior and Clr and very strong, and I wouldn't run a group without them
I just came back after a break completely missing RoS and within a few hours was able to get my shit together and go finally kill the Hero of Kor-Sha Lab Atrebe event with my little 105 group of silvers (I golded my tank today)
I think your group setup looks very strong. Good luck to you!
