Nuts, I figured that might be the case after the comprehensive thumping I got. I was hoping it might be a spec or gear thing but I doubt it now.

A trio now looks to be a bit of a no mans land. Over powered for questing but can't clear a dungeon. There is no way my machine could run 5 clients and at the moment 3 is enough to handle.

I might try a role where my Rogue specs in to bard for more healing and come back in a level or 2.
