Yesterday i played a game of spears on the map "East river" i think it's called (the one with waterfalls and sometimes bugged out sound). While going for the spear with a crashed helicopter on a slope nearby, i used powerslide (just because it's funny on a downward slope). Anyhow, i slided right into an enemy player around halfway through the slide...

What happened was that i got a melee kill and "midget wrestler" (melee kill while crouched) for sliding into him/her (and killing him/her). Anyone know it is intended that you can powerslide other players to death or simply just a glitch/bug?

Yes. You can power slid people to death ~ you kick them, like a melee hit. It's not a bug.
