Afaik, TTTLA HATE the term of Anti-pk, and prefer their own term : lawyer. Their roleplay is to kill every outlaw, which means every character that broke their rules - attacking them -. Of course they have to kill pks, how can players break rules except if they attempt to other's lifes ? And by doing their duty, they also kill players. So you can say they are pks also. Please stop thinking about anti-pks vs pks combat, everyone knows its non sense to summarize players behaviour like that in such a game.
About number : TTTLA are happy when they got 10 players from their side. That's because of alliances, and people like me who wanna defend Redding, that you had to face such huge number. Anyway, this fight was really balanced. If Rogues spawned a little bit earlier, helping their muties, they would have powned us all.
