yeah, the L80/L85A or whatever (medic's weapon) is pretty cool. it has pretty much the same damage and accuracy as the m16 but the addition of semi or full auto is awesome. instead of tapping the mousebutton with 3 shot burst when assaulting a position filled with enemies, you can just hold the button down and spray.
the aiming reticle is a little hard to get the hang of at first. when you zoom, instead of a single dot or iron sight, you get a single vertical 'hair'. aiming is pretty easy, the tip of the aiming hair is exactly in the middle of the scope. i just line up the enemy with it and shoot. the gun is good on medium/long range also. you just have to aim 5 pixels higher and to the right for really long range shots.
i've been playing a LOT on tacticalgamer.com servers, i highly recommend them for real team play. since their servers are unranked, the ppl playing are serious about the teamwork aspect and not hellbent statwhores who seem to clog most of the ranked servers.
