I think due to fall in dynamis currency price for some time already its a terrible money maker. Possibly farming spark even outside gain should net more money or currency purchased at the end.
While accurate, it's kinda not the point (I think). I don't know why you would
want to farm dynamis (boredom? ease? personal goal to earn without buying?) But you don't really need a reason.
You'll make a lot more simply farming crystals and sparks/accos are supplemental lol. And there's none of that proc ***.
I watched the video, good tips. The only thing I would mention is instead of trying for literal minutes to proc a mob, just kill that one and move on. Time is money. (I don't totally agree with the use shitty daggers either, more kills is more money even without procs but I haven't done it in like 4 years, I don't know how true that still is)
