I would so laugh if they decide to patch the treasure chest cheese and then reset everyone back to just 1 key. Especially on everyone that has 10+ keys from exploiting the cheese about how the loot chests work. Or maybe make it where there is a hard limit of only 5 keys per account, not per toon and vault. So basically everyone that is doing the cheese is just beta testing for them helping them work out the glitches in the system before HoW goes live and they can be used.
