And that's why the point that David tries to make over and over that "it's just a crutch" is silly. Because, until now, the only people that have stated how overpowered it really is and that have played the game...are MLG pros. And those guys, above any, are going to be the ones that know how to use the type of information that PV gives you.
So no offense to David or his skills, but I trust the guys that know how to use that information better than anyone else when they say it seems overpowered.
Now, I think it's been nerfed since the E3 build, so now it's just a wait and see.
I don't see how its overpowered if it's optional for everyone, If its so good then they can all use it and its problem solved.
Lets be real for a second, MLG guys felt strongly that AA's screwed with what Competitive Halo was to them that's why at the very most jetpack or evade was a map pick up. Its also an entirely different ballgame its essentially apples and oranges when you compare MLG to Halo Multiplayer. What is overpowered for them is not going to translate into every other game.
As it stands it seems PV is nigh useless for someone who can read the radar well, (Again MLG plays without radar) so for them it was a "OMG I CAN SEE EVERYONE" when for myself who plays and likes radar, based on the footage iv seen my reaction is "eh ill take something that i can actually benefit from".
The whole PV is OP stuff seems very very hyperbolic to me, we wont know the real shape of AA's and how powerful they are until the game ships but if it shipped right now i cant see PV being used as actively and devastatingly as you would expect from something "overpowered"
Edit: just seen ellis post, now i look like a david slurper.
