Hm. My signature move is capping the last point of a pushmap as spy
in front of a sentry.
Works best on Badlands, as the cap is small and semi-enclosed, also a good thing to do on well. rarely works on fastlane, though.
At one point I just noticed how damn fast the last cap happens. Also, in many pubs, people don't care to stand on the last point, especially if there's a sentry in front of it. So what I do is disguise as a
friendly class, get on the point cloaked, wait for the sentry to swing away from You and decloak. The fun part is, You start capping immediately after pushing the decloak button, whereas the sentry starts shooting at You only halfway through the decloaking animation. On the last cap, that is enough to cap half of the point. The rest will be capped while under fire (possibly moving a bit in the direction the sentry swings, or near to a wall to avoid some of the bullets). You will most probably die, but the game will be Yours
In my patron server, they actually increased the capping time on the last points of pushmaps. The unofficial reason was "Because it's bloody impossible to defend when Sylvine is around". Reading that sure made my day XD
edit: Damn that f and c keys being so close together! Of course You want to be
capping in front of the sentry, not
fapping XD.
By the way, works well on payload maps too, when they're relatively close to the last point. Just suicide-push ike that a couple of times. The only use I've ever found for Cloak and Dagger.
