I've seen it posted before, but this really needs to be implemented. Give the players the power to create custom PvP games for Blast Network and Lockdown. (And any future PvP games too.)
I'd love to go free-for-all or teams against fellow guildies and/or friends in PvP. I bet this would increase the PvP population a good bit.
Ignoring the fact that OOO's would most likely need to deal with their servers beforehand to handle the existing horrible lag and the expected PvP population boom.
It may be a bit wierd but how about a wager system? 200 to get in but... you can bet a certain item,cr,etc.
