I can see that already. "In order to apply to *srsgamersguildname* you must be in the top 20 of the all time PK rankings". And here rise the weird phenomenon of low level, weird named characters (weurfuzfwezfgew, money1, Morai3, reqwqwe, try1, alttttttttttttitties, lelolelo34 etc...) who, by coincidence, go white named out of SZ, and by coincidence, get killed by that exact applicant, and by coincidence, they do not really stop, they keep on going out of SZ even after the 10th death by the same person, who is an applicant, by coincidence, and by the next morning he will be, by coincidence, the toppest player ever. EVA.
Why do rankings matter so much to people? It doesn't exactly show you know how to play your class or anything..Congrats you mashed the buttons on your keyboard faster than 10 other people and play this game more than you probably should. Would you like a cookie?
Positive impact? You high? The kind of competition on here doesn't result in positive impact. It results in useless drama...
+1. I think this will encourage more players to go hard or go home, which in turn would increase the activity on the server (even by a little).
...and for the fact you don't exactly get rewarded for being ranked at all, then what's all the fuss about? If the top 10 or 20 that rank on the PK boards got some sort of reward, it would make sense and maybe be a little more understandable.
