Welcome Back! Assuming you took around a year or so off because that's how many stones I had left when I got back.. And getting back, it doesn't look like it takes 1600 stones to make an empy so I'd just ignore Aeil.
Lots of stones usually means lots of Empy because you have no reason to enter abyssea other wise any more. My brother and I have duod about 8 empys now and we would be considered "Casual" players compared to most on our server. We both have 1k+ stones as well .-. yay stones! (if only we could sell them)
Seems to be common anymore.. alot of people have way over 1000 stones.. I have an empy, i may have to make another one after i finish my mythic just to put some of my stones to use.
