In 1.3 jeb added the ability for items when dropped would all go together in a pile but it would be one pile, i was thinking, back in beta 1.8 they added xp orbs but when you died with a lot of them it would cause severe lag and because of this they made it so that not much of them were dropped when you died, but since they added this "pile" ability for items shouldn't they do the same for xp orbs and give the full amount back? i find it annoying when i die at level 30 and only get 6 levels back.
