First of all, where are they when they do the daily quests? That's right, out in the
world. So I would say they succeeded quite well with that. Secondly, why would you go to Orgrimmar? All the MoP vendors are in Pandaria, if anything the Horde/Alliance Pandaria base. Thirdly, you do get rewards from Heroics, I got 466 Item level on my lock and that's more than enough to enter normal mode raiding. Fourth: Valor points can be spent even if you don't get rep, it will be possible to use to upgrade your gear's item level further.
So these events would work something like daily quests..? You go to them once per day... and complete a task?
