For me it'd be
1) Lucy - Sexy and funny, no BS fights unlike everyone else in team Natsu.
2) Erza - Good on her for not giving a crap about Eileen. Her fights are BS and her speeches suck but i enjoy her personality outside combat.
3) Gray - As interesting as Erza is, with less cringe. Used to be tied number 1 with Lucy before the fight with END
4) Happy - Funny guy, loved him as a giant. Wanks Natsu a bit too much though.
5) Wendy - Not interesting enough to bother thinking about, and her sudden mastery of enchantments irks me.
6) Natsu - As cringeworthy as Erza without the sexy bod. Casually deciding he's "just human" really pissed me off, dont act like that shits obvious, its not.
7) Carla - Even more boring than Wendy, i'd like her better if she mastered her precognition instead of wasting effort achieving a pointless human form.
