Do I need to pull Azura right now?

The more dancers you have, the better it is. Trust me

It would be beneficial to get another dancer but you should wait and see if the new banner interests you at all.(This Tuesday night, the trailer!). Also we never know if we will get to evolve Azura's weapon to the Blessed Lance!

Apparently, the more dancers you have, the better.

I have 2 Ninians, 1 Nohrzura, 1 Azura, 1 Flyzura, 1 Inigo, and 1 Olivia that I was merging together at 4*s (+3 3* Olivia's), but the only singer/dancers I use is Nohrzura, Flyzura, Inigo, and sometimes Ninian, and out of those units, Inigo is the only unit that actually battles units because he's a mage and can safely snipe some units that don't have Distant Counter.

If you want to get more dancer/singer units, then fine, but it's not as much of a necessity as everyone's making it out to be.

Having more variety of dancers is always a plus, but at least wait until the new banner is revealed, by the time it drops it should still have like a day left.

More dancers are never a bad thing. But they are not entirely necessary. I only have 2 (Ninian and Olivia) and I do just fine with them alone. Having a few is essential, but having 6 or 7 isn’t, although it’s not a bad thing. I’d say wait though, see how you feel on the upcoming banner before shelling out to try for Azura.
