Lol they should just refund all ingots for ppl who spun the wheel ... they lose no money anyhow... what a joke of an event.
It's basically designed to trap you into thinking your getting a decent reward while competing for a rare ninja but the truth is your spending money for nothing (eventually)
They just want to put 3-4 people at each others throats topping up for competition over a ninja.
I'm literally considering never spending again after they rig a event mid-week following being called out on shady practice.
