Also, we're supposed to be brainstorming ways to make this work, not saying it won't work. At minimum, you should describe why it won't work, and listen to people as they take your advice and see if they can use it to come up with a solution.
Read the thread. Theres a number of solutions, which can collectively be summed up as
'Make the life of a wolf very, very hard'.
However, when you do that wannabe wolves whine that their preferred playstyle of making other paying customers victims isnt being respected.
Wannabe wolves want all the reward, and none of the risk. They want all the benefits of being a sheep when they feel like that, and to be able to put on wolves clothing when they feel like that (note the popularity of "PvE alts" to fund PvP).
So, you either make everyone a wolf - World of Tanks - or you make being a victim voluntary - PvP flags/zones.
Either solution doesnt give wannabe wolves their stream of victims, so they come to threads like this and whine.
