I used to be a skeptic like you, but then I took a friendship to the knee.
I mean... I used to wonder what the big deal was. Eventually got curious enough to try it. Never looked back.
It's not for everyone, but it's surprisingly good--it has enough cheesy stuff you'd expect, but it's surprisingly well-written. It's not childish drivel like the title "My Little Pony" would have you thinking. I'll leave it to others to explain why some might like it. Though I agree that it's a great change from all the negativity in the world.
Anyway, I'd have to go with a Fluttershy build. Or, what would a Luna build be like? Illusion, Alteration, Destruction sounds appropriate. ...complete with 0% Shout cooldown.
I am a fan of My Little Pony. You do not have to watch My Little Pony.
