@Skull8Ranger Why not spawn as Rao ? A hack of a plane scares them off and damage them. If no one ever plays as Rao then yes they have a fun time killing you all. A hack makes them launch flares and run for cover. Problem on a team - all wants to be assault, medics and supports - but not very often Rao. When I think a map is controlled a little too much in the sky I always switch to Rao and start hacking them.
Stingers has zero effect on them since flares in this game is way way too effective. I also tried Lis severeal times - but I suck at those missiles and choppers ha ha ha - always only hit the ground vehicles - so here I need way more practise.
Try Rao next time !
