What a wall of comments...
As of Ish, I acctually thought ish == im_batman. Im a bit confused atm since now I fought with someone totaly different.
As of the ability to add/remove and change buildings, it is nothing near top priority. Its a nice thing to have and I basically just implemented it since the backend was already present due to mob editting and such. Basically, there is no difference in changing mobs or buildings other than the files being slightly different.
However, the only good thing on being able to edit buildings is the ability to remove them. There are some unused areas in rohan which are currently closed.
Note: Ish, we are not building our endgame around craftings. There's been alot more changes to the crafting pipeline you knew. In other words, we aswell have proper forging grades and crafting as a real option.
