In terms of pk quality, Mizochi was good. She gave me a hard time, very good at using arrows, bushes, bombs, also suicide in an instant. She was the only person I couldn't beat in the open environment pvp. and she was a nice person if you don't see her in the pk zone.
During pk riot in 2014, I witnessed players like Twilit grab 7-8kills before he gets killed. it's pretty hard to maneuver in pk riots and make sharp turns.
I wouldn't leave out EP from 2012. He was like a God of Towering figure at the time. His stats were so fancy back in 2012.
Speaking of pk and towering. I never saw Thallen in pk zone, cause I lost my pk interest when he was leading all those towers. Can someone tell me how he was as a tower leader or pker? He got like 150k kills and own multiple 1k hats, but never got a chance to judge him on pk field or tower. Why is he not mentioned in OP?
