You obviously do not know the scope of what is being discussed here. It's not a 4 chest run near quest objectives, and if you are doing that, then your farming is really getting screwed. What we are talking about is a 6 chest run in pretty much a straight line string that you can run beginning to end and back in 5-6 minutes. You make 120-180k per single string run of 6. Roughly 1.4 to 2.1 million credits every hour.
Also to give you an idea of how bad it is, I know a few people that have made the following just since it has been live. 15 million, 12 million, 70 million, 2 million, 8 million. That's just people I know, but there are people in every instance all day and night farming. Sometimes you fight for it, sometimes you take over someone's shift. I can hardly imagine Bioware wanted single players to attain those kind of credits easily. Maybe if it were spread out amongst players it wouldn't be an issue. All they would have to do is randomize the location and the spawn time and it would effectively end it.
