I played Wotlk and got really bored with it honestly, I wanna switch to MoP but I see it has low population and I am okay with it, I just wanna know if that small population runs raids,bga, arenas regularly, does RDF work and stuff like that...Thanks
RDF does work and there are a few guilds raiding both horde and ally side. All LFG content has enabled mercenary mode to help with queue times so pvp is also active although you will be running into the same people often.
