If you are hiding and they are unaware. They might try to kill your teammate coming and you can ambush them inturn before he lands. Works both ways.A lot of people don't think about where they are jumping to. If they're jumping on the front lines without stealth jump, they're asking to die. Sometimes I will jump to a sniper on a safe perch who looks to be safe for a 10+ seconds. Mostly I just swim to the point I want to be, and avoid super jumping altogether. People who jump will be punished. I punish them. And they'll learn not to do it. I'm constantly amazed at people without stealth jump jumping to me when I'm engaging an enemy and trying to hide. Not only have they probably killed me, they're going to die the moment they land.
