Here is a deal...
An orgonization with averege players lvl 50-75 builds ql 75 controler now someone decided to attack that base and among with few lvl 50-75 people they brough few lvl 150+ healers who just stand there and heal those lvl 50-75 people.
We didnt get to this in beta couse everyone was equal lvl but i suggest that you remove high lvl people from low lvls areas like crowed control removes people from overcroweded areas.
Ofcource there should be some sort of a timer lets say 2 minuties that you can be in the area then you get warped out if you dont match lvl requemnts of the base.
