Hello, I have a Wind Mage-Knight Which i use for both PKs and for Questing, but i have no idea which pet should i get her. There are so many and it's hard to choose, I was thinking of Charlotte due to her speed and her skills.
Is she a good pet or should i go with another pet?
Thank you for reading. ^_^

Charlotte is a good spd ride pet :)
Personally for me pet that deals damage is good, Fred, Roca, Niss. Something like that, but that's just my opinion :) (no pro in pk/quest but they're useful in quest)

Again it really all depends what you want to us the pets for. In your case since your a wind knight and pets that are close to your speed will have to be winds or scrolled to have a lot of agi. Charlotte is decent but mainly used as a ride pet. There's 3 pets I would recommend for you.
Qlaya: decent spd good seal rate and ok skills and burstable. I have this pet on my earth knight and she helps a lot when I do quests and if you can get her a spd ring she can easily get close to you in spd. Try scrolling her for agi con and it and your good with her.

Clive: strong, good multi hit skills after rb, a little slower than other wind pets. Clive is used a lot in pk and he is also a good questing pet as well. Only downside to him is that he's slower than most wind pets unless you scroll him to spd. Not burstable

Lastly hayate: strong , has a non element atk, and a 2 person multi hit attack. Hayate is like Clive but she is definitely faster than him. She can be used as a quest and pk pet. Not burstable

Those are my 3 suggestions. Again all three of these pets can get close to your spd with a spd ring or of you don't have the money for Item mall stuff the just use the spd necklace from clive's death quest it adds about 1/3rd of the pets spd to its current spd.
