Current rate is like less than 1% so any change would be marginal at best. Issue is balance, because sure at one prestige we could slightly increase it but how high could we make it al like 10th prestige? At that point anyone prestiged would have ultimate rule over crystals and kill the market for them and in tern, a large part of the server and economy. I am looking into buffs for prestiges but I'm not sure what they'll be yet!
