now I am sorry if this rises a sour note for any one and I dont really know all that much bout programming and how it will affect your MP games but couldnt you just sorta rewrite the code there:
--always display item prices; offer better prices and rare levels at npc traders
--Advanced:
--better quest rewards +(1-2) rare levels
mgr.createSkill {
skill_name = "skill_trader",
advance_level = 75,
min_level = 1,
mean_value = 300,
advance_mean_value = 450,
skillgroup = "SKG_WORLD",
adv_skill_name = "skill_master_trader",
(as cthulu had showed(sorry for the probable misspelling))
basically what I am sayin is that couldnt you change it to make it either higher or find a way to make it that it will drop yellows or sets all the time(dont know if sets are yellows have yet to get the game)? Or is that little tidbit of rates of drop hidden somewhere else:) if it is at all possible then you could make it a way to farm items in SP at least and then transfer the gear to whoever you want when you go to MP.
