I don't think a tall (regular) pot is necessarily problematic. The issue you face with that kind of geometry relates to water, and the ability of the soil to dry out in a timely manner, but an unglazed clay pot will dry out fast no matter what (given strong light and decent air flow).
This plant does not enjoy having wet feet, and you can definitely kill it by overwatering. The azalea shape is my usual safety measure when this issue presents itself.
I don't think I'm the right person to ask about low humidity situations. Our humidity here averages 70-80%. We get regular coastal fog, especially at night, and only when the wind reverses (which it does occasionally but only temporarily) do we experience low humidity.
The issue with misting is related to the issue with overwatering. You want the soil to dry out before you hit it with more water, and misting will slow this process down. It should not be a problem in moderation, but it will become one when you go too far.
The terrestrial bromeliads (which span a range from Mexico to South America) are different from their epiphytic or rainforest brethren. They certainly do not mind high humidity (like we have here) but they definitely do not require it, either. These plants are dry growing in nature and they can actually tolerate 6 months of drought when established in the ground (the species being discussed here, anyway). You are more likely to kill by overwatering than underwatering, I would think. Speaking as a chronic underwaterer.
