Yes, but if you care about the leaderboard and getting optimal PKs then why aren't you also doing what they're doing? The only logical reasons I can think of:
- You think it's boosting, which has never been confirmed by staff so it's basically an opinion or "moral compass" type of an issue
- You don't enjoy it
I find mob PKing to be pretty boring myself, felt like clawing my eyes out 12 hours into PKing Graal City, but if others want to do it then I feel like it's not my job to tell them they can't
Mob PKing has always been a thing, long before the leaderboards, I'm sure you guys remember EP getting 9.6k or 9.7k daily? That happened at a mob at a tower and it was celebrated, so the sentiment seems to have changed for no apparent reason
