When you first start out, I am unsure if it is still possible to profit (I haven´t hunted those mobs in a while). You start at a major disadvantage with looter levels being so low.
That being said, 2k kills is not enough to come to a conclusion. I have had 35k+ loot instance streaks where I was below 90% return, only for it to work itself out in the end.
Like I said, I am unsure whether it is still possible to profit as a fresh toon, but I will give you some tips and pointers that would have helped me out early.
1. Keep track of your average MU.
2. Keep shooting. (This is a bit of a cliche, but since "cycles" are so long, it is valid)
3. Test different things.
And for the future:
The things people suggest in public places that you do is usually not the best thing to do. (Unless it is really boring`)
Your goal in the game, if you want to profit is to find a profitable opportunity. Profitable opportunities usually don´t grow on trees, and when people find them they are unlikely to "spill it" until they´re either bored of it, or they find a better opportunity.
This is a PVP game. Do not trust anyone. Take what people say to heart, but do NOT draw conclusions based solely on the statements of others. Gather your own data.
Now, to circle back on the first points:
If your goal is to profit, either short term or long term, your goal is to find the highest average MU and cycle as much as you can there, until the opportunity is gone. (There are facets to this that you will learn over time with keeping track of market data. E.g. What is currently the best average MU mob for you to hunt may not be the best long term MU mob to hunt)
