I can understand that.
I do a lot of mining so I have gil to blow. There really isn't anything else in the game that one can spend gil on at the moment anyway.

I am going to get the relic on the off chance that they make it upgradable often enough to be worth the investment.
It's a gamble, but I am willing to gamble on Yoshi-P's words. I have been since launch anyway. lol
