well if you wanna make 300g a day with no skills the most obvious way to do it is to do your dailies! do your IQD, Skettis, Ogrila, Outland, dungeons dailies. and youll be rolling in gold in a week. and also youll be getting a lot of other items and such from the mobs you killed. everyday i make just 100g off motes/primals and i DE my greens. you can also sell netherweave cloth. i know a lot of you are going to be like durrrr everyone knows this but surprisingly a lot of people dont know how great doing your dailies is. and it only takes 2 or less hours to finish all 25 dailies excluding dungeon ones.
