I still imagine looting with 5box is a serious pain in the ass.
I'm missing something here, because I've never found looting any more of a pain with five characters than with one character - it's just a whole shed-load of bodies to click on if you bother looting when you boost.

When your main's full up, either offload the crap onto one of your drones or rotate the looter around until they're all full.

You can also loot with the new "interact with target" keybind, but you still need to click all those corpses.

Personally, I only loot while my booster is on down-time (I used a mage, and she needs a drink between pulls) and leave everything else alone. The low level instances especially - certainly up to and including ST - are a waste of time loot-wise, even for enchanting mats.

Somebody here once did the math surrounding time spent looting vs. time spent doing more boosts and therefore reaching high levels quicker and making even more money, but I can't find the thread at the moment. It was a fairly compelling argument against looting in the lower-level instances though
