I just want to see someone QUALIFY for this class. Having to prepare/spont. cast NOTHING but Haste spells for one whole level is just funny to think about.

That's not really a requirement. They can still use other level spell slots for other spells. It's only their third level spell slots they need to hold exclusively for haste.

Note that a sorceror automatically qualifies if they take Haste as their 3rd level spell at level 6, because it's the only one they get.
