farming char for gcm

just wanted to ask what lvl is the best to do gcm (red but also superior included), only farming profit wise ? 156 or 168 ?
thank you in advance.

 

HM12 (156) u can do green superior, first mobs is green , for red run is orange

 

Btw, wich role is more faster?
With decent items, and what build?

 

U mean green superior from ingame or item mall passes ?

 

for farming yes like gold coins 4th aniversry, easy at HM12 with green pass from ingame (idk what different item mall pass), no need good gears, all role can fast too, better ck mybe, u can kill with 1 skill
