Trolls and jerks using Roll for Items as a shield.

I think the real thing to adjust is the time you have for rolling an Item. To know if you need or not an item, you can do it in less than a minute.

...This game is all about speed runs at the minute so no-one stops for anything especially loot...

Duties are a party collaboration. If some people won't want collaborate it is their problem, not system's one. This is no different than tanks that start running even when healer started casting protect and them got los and dying on the wall ten miles ahead.
