Pyro:
Festive Flamethrower - Lookin' good while barbequing, the manly way to do things. No real down sides, burn the heavier classes, and it airblasts the pesky scouts away from me.
Strange Reserve Shooter - Scout dodging all my fire? Simple, quickswitch and fire a few times. Done deal. I slay enemy pyros with this...
Strange Powerjack - I get to smash stuff, and I get health for it. Simple as that.
Scout:
Strange Soda-popper: Besides how awesome this gun looks, it's basically a force-a-nature with out the annoying kick. By itself, it does amazing, but with the crits that it gives you for running around a lot is just a 10 point bonus.
Strange Mad-Milk: Who needs medics? I just saturate my target with this, bounce around them, and shoot! Free health!
Sandman: Pesky soldiers and snipers, always trying to kill me from across the map :<. Simply aim above them, right click, and watch them get bonked!
Sniper:
Sydney Sleeper: Douse your enemies with humiliation from hundreds of yards away, humiliate them to such an extent they drop dead.
Strange Razorback: I never worry about turning around, in fact, I don't want to. Add to my backstabs blocked count, I don't care!
The shashanashashahsanaasha: Besides the rough name, this is the perfect melee weapon for the sniper. It looks menacing, and crits when you're below 50% health. Which really is a perk, regardless of the -25% damage done above 50% health. If an enemy is close enough for you to hit them, odds are you're below 50% health, so in the long run, it helps.
