In light of recent topic Rest Stop Outside Mt. Barricade, I also wanna suggest the addition of a rest stop a bit closer to these dungeons. All of these require one of the longest walks from town and the use of two or more HMs, and there are no rest stops near this west part of Exbel.
If I could make a suggestion, I’d suggest using this tent south from the evolution chamber (currently blocked off and has no real use). This would provide handy access to a storage and assembly which can be found just above, and would shorten the walk distance a bit to these dungeons.
