I'm a commando healer with a mix of columi gear and champ gear. I sit at around 18k hp fully buffed. I can tank 2 dps at once and not die. When I run with my vanguard friend and have guard on me I can't be killed unless by 4 or more dps
Dps meters allow for min / maxing and rotation tweaking. It adds depth to character development for people who want that. Its useful for a guild pushing top tier content. If you don't like it, don't use it.
Hard mode Battle of Ilum: Killing the last boss doesn't unlock the chest. Another bug in Directive 7 is the shield on mentor won't go down after the 4 pillars are destroyed.
I got to level 50 on the 18th, been farming heroics / dailies and doing pvp since then. I am in almost full epics. I still like this game and look forward to logging in everyday.
