Trying out Spy some more. I've already clocked about 8 or so hours as Spy, but I'm still absolute bunk at it. I'm trying my hand at the YER playstyle, and swapping that out with regular knifing if I have to get behind a turtling team to sap their turrets. Playing mind games with Engineers is a lot of fun, too - the ones who hang back on the CP maps and try to build up their stuff before bringing it to the front lines. Stab 'em, sap a few things, wander off with the Cloak and Dagger. The second any of his friends come along to help him out, though, I back off and go do something more productive, like backstab Medics, but it's just fun watching Engineers whack at their gear, then randomly whirl around HA CAUGHT YOU Oh wait no one's there... welp, back to upgrading.
