[PvK]

PD (or unit-killing) experience was at least patched way way down. However I think maybe there may be a small fraction given for destroying units of some kinds. You might have to use non-PD weapons, and it's certainly not 1:1, and might be limited to certain types of units. I seem to remember getting some very limited experience though when fighting someone use practically all drones and no ships.
