The speed for heroics is insane, I have soloed through heroics chain pulling mobs and the whole group close to 6k gear score and the Nexus still took about 20 minutes.
The logic is good BUT it is still VERY economy dependent, a good example is the transmuting of saronite to titanium, I did this on my server and ended up with a lot of the bars not selling at all, so VERY market dependent.
