The only one who consistently won't get ledge kills is Vader with his Choke ability. Others will get it most of the time. The reason why sometimes fails to grant the kill is that they can touch something on they way down after you pull/push them so the game can't properly decide the exact reason why they fell off the map.
No Sir, that's not true. I also pulled people as Kylo Ren directly off ledges without them touching anything before and it didn't count as kill as well.
Play some HvH matches and test it.
@TRlALON
You're right. Although @Szaby59 's assumption is a good one, I have already seen the opposite, so I ruled out this reason: I used choke hold on kessel, the enemy player didn't fall, but almost did. Then friendly kylo came and used Frenzy, which not only hit and damaged that enemy, but also pushed him a little that he dropped to the abyss. And I got the kill, but I didn't do anything to that enemy after the choke hold that failed to push off that very enemy, and he was damaged by an ally of mine after my skill, and before the enemy died, which should have taken the kill from me.
So the BUG that doesn't grant the kill when it should is still a mystery.
I didn't have time to do a round of tests yet, but I'll try to do tomorrow.
Another reason why sometimes you don't get the kill as Vader choking someone of the ledge is because players have enough time to respawn which doesn't give you the kill
@HomerSpinson You mean they use the respawn button to commit a selfkill? Well, then like 80 % of all choked players would do that which seems very unlikely.
That'a stupid anyways, because in maps like Kamino it's possible to save yourself by using the WASD keys to maneuver your fall and land on one of the runways that are below you.
It's even possible to use the WASD keys as a brake (e.g. when Maul or Luke push you) so you don't get pushed that far towards the ledge and possibly be able to land on the last meter of the edge before you'd fall down.
Also, if you drop 3 people of the ledge and you get three BP messages for kill assist then they didn't made a selfkill.
