well, in the end there will be a static price, since dynamis *does* cost 500k, no ifs ands or butts, every time you enter. the price will remain a little higher for profits sake, since no one does it for af expect the tiny few, or it will become required that all dynamis shells were relic sponsored, if prices become so low as to actually lose gil every run. and sponsored dynamis to get a relic, is pretty cheap.
i wonder if i should buy my attestation and fragment now, how do you think prices on those will change?
