Tips for winning as Shadow in Shadowfall?

I've played some shadowfall yesterday and shadows are really leaving hard now. You're lucky if you get 10 shadows in the end - that's very hard to win for shadows. I guess just try to get a game with at least 15 shadows and then try to work together to kill legends closest to dropship location (you should know it by 2nd circle +-). Blue+ armor needs 2 hits to kill, so best to go at least 2x1.

If you try to complete the 25 dropship mission and don't leave when you are shadow, you should win at least once or twice as shadow before you're done with the escape mission (unless you really never die).
