2 healer set bonus from the blue line set is def worth it. Now the charge set though...
Iirc the dagor set ( dps ToO set) has the same setbonus as charge but as a 2 set bonus, meaning it's possible to go for 4 command ( sure strike inc damage) and 2 dagor while putting mits and morale on your essence jewel. This will increase the dps of your group a lot more. Havent made a build around it though as i haven't been playing a lot but i'm sure it's 100% viable for most instances/raids
