My biggest complaint is compared to the early planets, the later ones take so long (if you do all side quests, and I am completionist so I do) that I am utterly sick of the planet and can't wait to move on. And yes, Hoth is pretty boring traveling from one place to another nothing but white snow after white snow.

yeah, pretty much in pugs (pick up groups) be prepared for unpreparedness. As far as creeper guy, use ignore function. What I do if a heroic/dungeon is going badly is start marking targets and typing cc order in chat. Sometimes people listen, sometimes they don't. but most don't want to wipe repeatedly and will at least try
