I don't think I wasted any time or gil.
I mean. If I started one right now, then yes possibly, because I know I won't be able to finish another one before HW comes out. But my bow? I've had it for a month and I will still have it until HW comes out; having the best weapon in the game for that long isn't too bad.

So no I don't think it's a waste. (I also think the Yoichi Bow Zeta is gorgeous but apparently I'm alone with this though so whatever)
