well i love PK in WoW...

i say kill all the alliance
in other games its a bit complicated... in some its just pvp arenas and such... and again in some...well like in lineage .... too many :\
Depends on the game, and since i play wow and gw the most... ye i got to say i like it
Later on, when you reach your main goal... lvl to the highest possible lvl... you do some pk

... a lot of pk ^^
