Damage done is only indicative of Healing done. Congratulations on realising that Healing got nerfed this patch, and thus your over all total damage on warzone score boards went down accordingly.
Stop using your healing debuff unless you really want to cover a dot. Stop using your interupt every time its on CD and instead interupt key abilities. Make sure you're using your relics at a point of which they can't recover what you do. And if a healer doesn't need to kite you, you need to rethink your career choice.
Iron out your spec, ability usage, and companion usage, and you won't have problems leveling. It's not as faceroll as Inquis/BH, but it should not be difficult at all.
You must not understand how the soft caps in this game work. Stuff starts scaling as soon as you get a point into the stat. That means that after a certain point, the gain is ridiculous compared to the effective HP and offensive gains of raw stats from the PVE gear.
Wrong. Wrong. Wrong. Wrong.
In this current patch, the PVE sabers with proper +41 power crystals in them WILL be better.
Patch 1.2 will have to see just how much the expertise cap changes.
