^^ Do this. the Essences are much easier to farm than the binding powders. Since they introduced the AP and RZ ear, everyone is doing tradeskills and bind powders do not last long in the bazaar (your server may be different). To give you an example, I leveled research on my main char a few years before either of those came out. I just did it for kicks with no real end goal in mind. I was able to go from 0 skill to max trophy in only a few hours of time played. Binding powders were cheap and plentiful on the bazaar at that time. After AP/RZ came out, I went back on my alts to get theres and there were never more than a few binding powders available on bazaar at any one time. Certainly not enough to powerlevel like I had just done a couple year earlier. However, you can take your automated group and go camp a remote corner of some CoTF zone and get Essences to drop at a decent rate. Take a forager along too and have them autoforaging as well.There is a macro for that one on redguide.
