(2500 X 6 Excas at 0 discoveries) X21 = 315k, + the 100k for the Exca permit.
So with what you're proposing, you're losing 435k (if we consider a RR 650k) and potentially more time since you will need to win matches where on Excas there is no Win/Losses, just smashing rocks like a tard .
You would be ready to pay more if it's on PvP, maybe you especially won't mind. But that would create another unfair advantage for PvE players over PvP ones in this case as you'll need more effort to get the Reveal Glass.
Maybe Wally will hear you out, who knows.
