How about a Killing zone where monster spawn ultra fast and the longer you survive the more gear's upgrade mat you get from the Killing zone Reward ambassador which has all the gear pinned into difference map like:
Killzone(Blessed) where u upgrade demonic gear blessed
Killzone(Ravaged) from blessed to ravaged
Killzone(Divine) from Ravaged to divine
and more place via Teleporter just for another easy way to farm the upgrade stuff coz it not very easy to run around ya know and please upgrade the Chillzone to attract more people's to it coz deepholm sounds kinda like chillzone now, that all of it for now
i will think up another idea soon....
