You are on the right way now - heavy misting is not a need for every type of orchid. Depends a lot on the climate where you live.
The Miltassia Shelob 'Tolkien' is an Oncidium alliance orchid, which has water "reservoir": the plump stalks named pseudo-bulbs, at the base of the leaves.If these pseudo-bulbs are smooth and firm feeling, the plant is getting enough water.If they are badly shriveled, the plant needs more water.Cynthia's sewer method prevent over watering.
Cut off the old spike, the pseudo-bulb will not flower again, but will develop new pseudo-bulbs at the base which will bloom the next year.
Good luck!
