Tombs should have an end chest, but the reward shouldn't be zaishen keys. It's fine the way it is. Besides, PvE players have access to the zaishen chest.
If this zaishen key is for pvp people why does it give pve stuff?
Ok. We've come to the conclusion that the Z chest is for both PVP and PVE players. Now, shouldn't the PvE'rs be able to obtain keys without relying on PVP?
No. You can ALREADY buy keys to get it out of farming.
And Special, I believe this was to get people who play PvE to move on to PvP.
Not only that, but to give a reliable "Money now!" spot for PvP'ers to buy Guild Halls etc.

Buy them.
Zaishen keys should not be obtainable in PvE. They'll get farmed like crazy.
