The Dekane mines are a great place to level. Except that the level range it is effective to do so implies a support Ringmaster who cannot possibly get there.
This is especially true of anything past the 2nd door, as it requires completion of a quest to be able to use the teleporter. That quest is gated by level, and so by the time a Ringmaster can do this quest, there's no reason for them to level there.
The teleport across the chasm to the Blood Trillipy spawn is similarly gated.
There's entire swaths of the Dekane Mines that cannot meaningfully be used for leveling because of these artificial, ill-considered barriers.
The Suggestion
Reduce the level requirements, or eliminate the barriers entirely, or rework how this quest chain works, to allow support Ringmasters to enter the zones past the 2nd barrier (after the Pinky Room) and enable people to level in these zones.
