If a clan runs an epic battle that drops an item, with everyone in the clan having the item already except one, when an item does drop- do they automatically get the item? (or is drop rate reduced to prevent this person from getting the item easily)
The drop rate is person dependant, not clan. If everyone in the clan has the item bar one; when it drops the person that gets it is guaranteed to be the person who doesn't have it. But the drop rate doesn't change. It may seem lower, but that is because only one person is actually going for the item.
Nope. The chances are still the same if everybody didnt have one. Still 100% random. It is known to say that if no item was dropped then all of the drops that were going to drop were giving to somebody who already had the equipment.
They have a slightly higher chance than they used to, if they participate, but they will not definatly get it, no
