Hey all,
I don't think It would be fair to just move the mega stones away to a quest like that. You have to consider that there's many people who did spend a lot of time farming those 1000 AP and they would kind of get punished for buying them in the past.
(I m very low excavation rank and far away from getting them, so its not like I am one of those.)
So first I think that there must be a solution found for these poor souls. That's not really easy cause giving them the 1000 AP back and taking away the mega stones from them so they can re-farm them in a quest is not a solution in my opinion.
Where I can agree is that the price could be lowered, and people who already bought them get the difference back.
Still. In my opinion It is good like it is right now.
