Fix Discipline Training Grounds cooldown, please? Can I play the game?

[Marchutan]

Could you guys PLEASE remove the cooldown for Discipline Training Grounds? We get no rewards from that, it's just for practicing. We didn't even have cooldown for that instance, originally... This is so annoying. Imagine having to wait 20 minutes to queue for Discipline Training Grounds after geting an empty run. LET US PLAY THE GAME.
