fire cold heuksalsummary:
good all arounder, very good pvper/group pvper.
just eats more money due to speed drugs
light cold bicheonsummary:the good old basic nuker build, good for as an all arounder, does well in pvp and lvling.
But like all builds: snow shield dependant.
light cold bowsummary:fastest lvling chinese build because of throwing around such high damage-> pve king
lack of survivability makes it less of a pvp character though, so unless it is equipped with +4 or better armor you might as well stick to grinding and group pvp.
edit: and i'd go for fire/cold bicheon
great defence+block rate , debuffs give you enough attack
