Well, I dont think so. And that because of several reasons:
1. Low pinging gives you an advantage.
2. Necros with horde minions have an even bigger advantage.
3. People can just sit back and wait, maybe with horde minion, let others fight and die and then go and loot.
4. When you die in the end of fight or when box explodes you have barely chance to get anything.
My suggestion would be that everyone doing some damage gets some loot in a corpse. Let the box explode and poison the people after the stranger dies. Let everyone doing damage get a random loot with someone getting the box.
But thats only my suggestion.
