you sir, are my new favorite member.
here's the rundown; AZ is almost purely non-cqb. I would suggest setting your load-out up for somewhat ranged engagements. I mean, there is the MTT UAC, they have some cqb action. then there is the new CQB arena opening up down the street from my house.
but other than that, I havnt been to a game where a cqb setup would be better then one designed to give you some range. we do have a pretty good variety of AO's out here, you can go from being in the mountains with trees and snow everywhere one week, then find yourself hiding behind cacti for cover out in the desert the next.
oh yeah, last tip....get a hydration carrier
