I'm a fan of the different AW's. But my problem is the runes.
I have several AW's in my city, different lvls, but on average I need 19 runes to fill the ring (and with 15 AWs in my city I KNOW what my average is) The problem is getting the specific ones I want. Right now I'm at the end of the tech-tree, so all 24 AW's are unlocked. Meaning that the chance of getting a rune for the specific AW I want to build or upgrade is 1 in 24. With a need for 19 runes on average to fill the rings I need 19x24 =456 runes to build or upgrade the one AW I want.
With only a limited amount of ways of getting them that seems to be an excessively high number. Especially since one can't break runes deliberately or at any time. It can only be done when filling a ring and my AWs are not always at such a point.
So when the crafting appeared I really had hoped for a way to fuse runes or break runes without having to build an AW, or create specific runes in some other way (which may be costly, I'm fine with that) but its getting to be damn near impossible to work on this.
