I have been using my coins rather sparingly(roughly 10 minutes between buff expenditure) and get blanked 10-15 bosses in a row. I would like to see a copy of your script for those coins because it feels like you have each stack working in 5% or less on these things. If I had to say anything, it should be working in 10%-15% per stack. Also adding a timer onto the coins after the exotic particles are gone would be wise so we have a firm understanding on how "dispersed" we should be popping them. Also a clear estimation of how high our stack would be appropriate so we know what's going on with it.
