I think they already used the data when figuring out details for battle sprite perks and abilities.

For instance, I bet a lot of people reported Plague Needle and Biohazard to be useless, and so they gave Maskeraith a Plague/Bio crossover that's basically the most powerful attack in the game second only to Blitz Needle. Of note is how much better the cutter families became when you could combine them with abilities like quills, flame barrier and angelic aura.

Then after that, lots of people probably reported Valkyrie and Deadly Virulisk as being useless because family bonuses are worth less than weapon bonuses. Hence, sprites get +3 vs family perks but only +2 for weapons perks. I'll bet people still aren't using them. ( -_-)

I mean, I'm sure not. After people also reported MSI as being useless, they proceeded to put an MSI+2 perk on sprites.

This isn't to say that gear in itself isn't going to see a rebalance in light of that survey, but gear has already changed around thanks to the sprite update.
