I'm pretty sure, MWR for everyone is a dissapointment. Treyarch released today support for dedicated rental servers.
It includes rcon, item restriction, playlist, all shit people loved(or hated?) in cod4/bo1
I'm not sure, is anyone working on promod for the game, but right now it's possible to force prosim ruleset.
Do you think bo3 is a good platform to revive competitive cod?
