If it were me......probabaly assassin. I already walk up and scare people because I was so quiet. I could add a stabby stabby in there this way.
Assault. Lets see why: -Jetpack. Rated in the top 10 items in existance, 20 years in a row(*citation needed) -Multiple Grenade Launcher. So I can shoot a ton of explosives really fast? Sign me up! -Mine. Stick it to their head, and control their fate! Muahahaha! Also, blast people off the map with careful placement -He's clearly the ladies' man of the team. Assassin and Pitgirl just can't resist him...
Simple an Assassin If they let me be a mix between the Assaults testosterone and suave with the Assassins cool crazy weapons and moves. Basically a male assassin. The possibilitys are endless! Fart in a elevator while cloaked! Make out with an invisible assassin in the middle of a crossfire.... While she's on the other team! Throw a smock bomb at a tanks face and finally put two katana holes in his face! Did I mention making out with even more Assassins? Well you can cause there's army of them to take! The day is yours for the picking when your a male assassin. Oh yeah and pick your nose in front of pit girl without her seeing then invisibly strip her! Via dashing and slicing off clothe! See what happens when a guy gets the triclops helmet? It becomes freaking awesome.
Now that I think about it sniper would be a second just so I could say things like blue 33 south west crazy leg sweep on the wing side and see thr expression on my teams face I'd lol like crazy.
