Hit the wall at 271. Nothing I do increases my power level. Guess it's time to raid or move onto another game.
You need to do weeklies for "powerful gear" it's the only way to increase your light level. All other drops are stuck at ~5-6 under your current highest equipped level.
What I've seen some people do, is roll a second character of the same class, and do the quests twice a week. Apparently it caps out account wide at that point, and you can't roll a third. And you can transfer your highest level gear between the 2 alts, so that you're consistently upping your level.
I'm too lazy to do that, but I try to consistently do the weekly quests, and I'm at around 282.
