I support the idea, but something has to be done with Aldebaran alongside this. Having the same drops in that abandoned place and both highly competitive trans castles that break 2+ times a woe doesn't seem very fair to me. "Then why don't YOU go to aldebaran?" might you ask, well that's just moving the problem, LOA/DD is the only guild willing and able to compete with Behemoth, while the newer Revenga and NE fight each other in payon. If LoA/DD moves to aldebaran, Behemoth would just sit on their economy.
I believe heRO's woe population is still too small for 3 castles, the best solution IMO (as brought up here:
