I am not sure if i am suppose to write this ... but here we go:
google zranger, buy the bot 10$/month, sub to L2 15$/month and buy around 1200 ncoins from time to time. The idea behind giving money to NCsoft is ... u wont get banned
If cant run 7,14 or 21 clients without reducing background performance pls dont even try it!
Edit:
#few tips: dont try to kill other bot pts to overtake their spots; u can sell gold for $ to clannies (depends which clan u r in); once u have enough adena to buy the gear u want, pls try to invest into better gear for ur bots or buy items from AH and control the market(which requires coordination with other ppl from ur bot clan)!
it all comes to what u need the bot for? Grind ur main toon exp/sp,PvP scripts or adena?
