@KING JAIMY Haha, seems you two have a little bit of a story. However the range is actually not great, it's i15 and it has decent priority (only 4 active frames), i think you find it useful mainly because P+K has a built in frame trap, i wouldn't label it a troll move, you can get punished mad hard if you whiff it or if it's SSed.
7K on the other hand.... i14, tracks, amazing range, great priority and safe at max range, one of the best if not the best counter-pokes in the entire game, now that's a move you can troll people with right there. ;D
