Loot rolling is fine as is so long as they don't try what they did with Ridorana Lighthouse by making loot rolls greed only. This was quickly fixed (and the backlash was severe) so I'm assuming it's probably not something they'll risk again. It has worked fine since 2.0 launch. No sense in changing it or even making your suggestion an option. Something tells me a lost loot roll brought this on. We've all had that happen. It sucks, but that's just the way it goes. Random will be random.
