I have always been 2-3 levels higher than the quests I am doing because I complete every non-heroic quest for each planet, including the bonus ones. I find that it makes the bosses easier and I haven't had much trouble with them. So far, I have found the actual bosses to be easier than some regular elite mobs. Doc helps a lot, for sure. Once I got him PvE became much easier. I was able to chain pull strong/regular mobs without having to heal in between whereas before Doc I had to heal after most fights. Even some elites I came out with almost full health. At level 42 though, I am beginning to have difficulty and have to heal more often than I did right after I got Doc, around level 37. Did you have this experience as well? It's been hit or miss in PvP. Sometimes I do really well and surprise myself and other times I die quickly with the enemy still at half HP. For instance against a level 40 Sorcerer I fought last night on Hoth killed me while he was still at half health. The heals are difficult to damage through but I probably interrupted the damaging spells instead of the healing ones. I do notice a lack in burst damage. I've been Vigilance since the beginning and haven't tried Focus dps.
