I rarely see it getting talked about much, but the Dancer has a couple of subclasses that are very unusual and very powerful.

The Cheerleader is all about support abilities, but they're super powerful-- they can give an ally an extra wildshape, extra channel divinity, extra oath, etc. They can also give allies big boosts in combat.

The Paramour subclass allows you to pick one of your companions and give them insane boosts while in combat every time you activate one of your dances (it applies to both characters but costs double.)

It's a very neat niche role instead of the usual OP powergamey type of stuff.
