I'm a subscriber and the character I'm currently playing is level 21, I always find myself with a lack of credits, I use credits for everything and I barely get by, sure you earn credits through quests warzones and flashpoints but I don't ever get much credits, I want to buy credits through the Cartel Market, it would make my game experience more enjoyable. I would seriously pay $60.00 for five hundred thousand credits.
And a credit lottery would be a good idea too, some MMORPGs do this (SUN) and I think SWTOR should too, I'd be glued to my screen for months if I had one million credits to play around with. I just want ways to get a large sum of credits for buying stuff in the galactic market.
