I get that he is helpful to beginning players. I'm mainly referring to him selling stacks of 5 heavy synths for 1 strange coin. That means every week an endgame player with three characters can easily buy a minimum of 135 heavy synths with the 27 strange coins earned from the weekly strike. That's more than enough to use one for every boss encounter in every end game activity each week on all three characters. Just seems broken to me.
