I vote yes on this It'll be nice to see how well you stand out against other players in a fairer gametype. I mean, the kitpvp K/D system is entirely flawed, and very much depends on a players real life wealth.
I think your statistics include everything you have done on the server though... This would include kitpvp, factions, skywars etc. I could be wrong, but i think that's how it works..
I strongly disagree on assassins as its most likely you get killed within the first seconds by hackers.
Idk, I play assassination's when I'm bored so im honestly don't know how it would effect the community. Anyway its up to the Owners to decide
