I'd love that! It'd be cool to if you could interact with them, like a familar or something. So it feels like a companion. Maybe come out with different kinds/types that are capable of learning different things and help in various ways. Instead of it being rng. You'd still only be able to summon one at a time. Maybe one type goes along better with a certain class or build than the other. Along with having various skins in the pearl shop. The faerie is just sort of there, after a while you kind of forget you have one, to be honest. 

Hmm, I agree with most of it, but I'd love to have all fairies compatible with all classes, pls. I mean, my guildie has a pink fairy coz he loves her sass, while I'm all for the blue fairy for her color and we both would be extremely disappointed if we had to say bye to them because they are not compatible with our class.... Also it would be kind of hard, since as we hop from one character to other, we would also need to change the fairy all the time as well(i sometimes forget to change my gears and get killed by mobs, so the fairy would be the last of my worries ^^')... So, I don't see the practical use of it, however I love the idea of having some kind of interactions with them.... Like, we can interact with our horses(even if it's just one thing), yet we can't even say hi to our 24/7 companion.... it's frustrating :D

No, I'm not saying you'd get rid of her. That would really suck for all the t4 faerie owners out there. I'm just saying add more. Different types to add more flavor or variety besides just looks. Kind of like how we have mounts and pets with different functions. But you can only have one out at a time. She wouldn't go anywhere (disappear). Maybe have a preset saved for each character (the faerie is automatically summoned per saved preset of that character). 

i want my fairy to learn all the skills 

yeah, make them learn all skills and p2w rerolls for lvl5 so its a 1 time thing and never again

They need to do more with the fairies for sure.

PA pls, time to stop neglecting fairies!

Agreeing fully with op and the interactions would also be really really cool :)
Also like the idea of either fairy being able to eventually learn all the skills or we having the ability to have several fairy companions (1 out at a time ofc). Now it's poopy to not be able to have for example Tingling Breath with Inexhaustible Well after rolling all the "essentials" and as we are restricted to have only one fairy friend you just don't have it then or make an costly reroll if really needing the skills for something.
