Hi, Which items are worth selling to other players? Also is it always worth it to modify you weapon, or only at higher levels?

Hi, Im a lvl 30 shadow dps and im almost finished on alderaan. Since the class quests are bugged i cant level Åby further. Is it advisable to go to balmorra or should i pvp/heroics/flashpoint to level 32.

I have the opposite experiense, in my heroics, we cc 2-3 units tank engages another, tank then engage the cc with shortest remaining time. Im happy
