Gaming for sure, I like to watch anime too (obviously, come on, I am here.), and I also enjoy reading which is a major bonus if you are into RP like me.
Y'know, if I was a PKer... Now would be the perfect time to go nuts. The frontliners are all in the dungeon/fighting the boss. The strongest players are not around to stop stuff from going down!
Wild guess, either he refers to the potential (probably won't happen) PKing while he is at the boss, or you going PK mode or something :D My money is on the first.
