So let me see here.
You reach max rank and then you can choose a specialization to equip in your loadout. Each specialization has 10 levels. Each level provides you with a piece of armor in the set or a skin? And the last level unlocks a specialization perk that you can slot in to your loadout. These specialization perks don't stack.
I'm assuming that since its not a static set of 10 levels per specialization, but that these levels are tied into your overall player level, that the first perk will be quicker to max then your second, third, fourth, etc.
The earliest you'll see ANY of these in action is with 60th level players, correct?
Now onto the specializations themselves, most of them don't excite, but two of them in particular bug me. A team full of stalkers seems like a team full of wall-hackers, with each player getting an icon for their last killer as well as icons for their last attackers. This one seems pretty annoying to be on the other end of. This is also an ability I would consider stackable.
But the one that makes me scratch my head the most is the Operator, which seems to provide resistance to EMP effects on vehicles. I don't get it. To EMP you already need to have a plasma pistol on hand - is this really such a big deal that a power to make vehicles resistant to this effect was necessary? Just feels like a Nuh-Uh button that will just piss of any player who manages to go through the trouble to pull off an EMP.
Rogue also seems troublesome, as if snipers weren't bad enough. Hey, lets remove one of the defensive moves against them. Yay.
On paper I just don't get the point.
Limited Edition Halo 4s come with all eight specializations available at max rank correct? If this is the case I'd expect it would be a loooong time before seeing these circulated into the non-LE playerbase, not just a few weeks. Of course this all depends upon how long it takes to reach max rank and how long 343 wants to dangle this stuff out there, but I'd imagine it wouldn't be quick.
