In my opinion a few of these should be added in the Mining Guild.
The 3 Mith rocks are simply not enough (also aware there is an Addy and extra Mith rock just outside south door).
When rsce was launched we had more mith rocks and also addy rocks inside de guild, then we switched back to the way things always were. This is supposed to be an emulation from og classic, however, so I'm aggainst changing adding different features on the og map.
So I'm -1 here.
You can wait for event island, it has lot's of mith and addy rocks!
