I'm against KP in general because I find it elitist, but... look, I get it. Some people take the game seriously, especially the raiders and fractal folks. If you're doing Fractal CM speedclears or Raids, I get that you want some kind of proof that someone knows the mechanics so that your run has less chance of failing. I've done CMs maybe once or twice but I do T4s daily and I know how frustrating it is to wipe because one person isn't carrying their weight.
But seriously, people asking for KP in Strike Missions is absoultely ridiculous. I completed Shiverpeaks Pass and Whisper of Jormag twice today with PUGs that had 2 healers, some decent condi dps folks and a few randos just doing their thing. These things aren't hard. They don't give insanely high rewards and they're not really "super prestigious hi-end content". The mechanics are fairly easy to pick up, or explain in one or two sentences.
I've done the missions so this is not me spilling salt over being kicked from a party for not having KP or whatever. I just think it's stupid and discouraging to a lot of players that want to give it a shot.
