Seriously, what the hell was NRS thinking when they made this the prize? Did we not hear Ed Boon say we wanted to give you the best reward we could? Did they not think once that there a lot of people including myself that don't even use Mileena, or that she is already practically naked already in her primary? To make it worse, they just had to hype the prize up like it was the best thing ever, and Mileena isn't even fully naked! Yeah, thanks, guys, it's already bad enough gamers have this retarded-ass stigma that we are perverted nerds that will never see the sun or get a girlfriend, you just helped reinforce that with this "major reward worthy of doing 300 challenges" of yours...
This is definitely one of those situations where the journey is better than the destination (a hell of a lot better in this case). The Challenge Tower itself is amazing, can't wait to tackle it, at least.
