...Is open to public again.
The new location of my lair is now at Guild: Tavu, right near pad/portal and it was designed with crafter's needs in mind.
It has all T6 shops (+90 bonus) on the same floor for easy access and each of the shops should have at least 2-3 silos in operational range of shop's tools.
Crystalshaper and Gemworking are in range to the 3 silos above them located on level 0 and the one on level 1 while the rest of the shops are in range on the silos that are under them on level 3.
I was trying to maximize the useable space whenever was possible, so the access to lower levels is achieved through route: spiral, smelter, pawnbroker, spiral.
I hope the labyrinth factor is not to big, still the map should prove useful to the dragon crafters that will need the T6 bonuses.
