There are three that have caught my eye, here. And I can't for the life of me decide which one to take when I finally reach level 50.
Wetwork: I love assassinations so much I've already completed the entire Assassination commendation. They look awesome, and I love them.
Operator: I'm the driver. It's what I do, what I've always done, and what I'll always do. I drive, you shoot, we win. Considering this is the specialization that is for the sole purpose of driving, it suits me.
Rogue: This is a choice for the sole reason that I swear by the carbine. It was my favorite weapon by far in past Halo games, so the fact that 343 not only brought it back but lets me start with it blew my mind. This class gives the Carbine weapon skin, so I feel like that's something I should have. Not to mention in all things I'm a sniper, and Halo is no exception.
So those are my choices and reasons for choosing them. And input would be gladly appreciated. Thanks in advance guys. Hope you're all enjoying Halo 4 as much as I am
