In all fairness all items are currently about 90-95% overvalued, seeing that we players value them high, but in Mindarks eyes the only ever value any item will ever have, is the TT value. everything beyond TT value to Mindark is arbitrary, and everything above TT value is not secured. Say what you want, but if Mindark went tits up, you would get 100 dollars for a MM if it was full TT, Nothing more even if you paid 8 grand for it.
That said on topic, for tier 0-4 would mean it should be priced at what 60-75k somewhere? Seeing that tier 9 and 10 go for 80++
