Just a curiosity question more than anything else, what bosses people are spending their coins on. This thread is mostly concerned with people who use their own deductive reasoning to spend their coins rather than those who use Mr.Robot or similar systems that think for you on these matters.
Are you using them on the same bosses each week nowadays?
Do you factor in the number of pieces a given boss drops, or are you primarily after specific pieces?
Do you save one (or more) wildcard coins each week for progression bosses?
Do you horde coins to carryover to the next week for reasons other than saving for progression bosses?
Do you factor thunder forge with any of your rolls (ie: roll for a boss whose best item you already have in hopes of a thunder-forged version of it)
I've been using a coin on Megaera every single week (have yet to see that stupid trinket drop even once for our group, be it a regular drop or a coin roll from anyone at all in the group).
The other two coins I save for progression bosses, but default to Iron Qon (for ring) and Oondasta (again for ring, still trying to replace 509 hit/crit shit after all this time) should we fail with progression quota for the week.
I have yet to see a thunderforged item looted by any player from a coin roll, and while I know its been stated to be possible on paper, I don't feel the odds are favorable to trying for TF weapons.
