looking an an updated pass on the roster and what i've played since returning, my list of characters I really enjoy is actually quite large, its more than double than even the ones im so-so and the ones I dislike combined.
In fact, the ones I simply do not like / wont play is quite short so far, only 4, but im only counting the heroes I've gotten to 10 (at least), and a lot of the ones I havent is precisely because I dont really care for them and thus have struggled to put a lot of games into them, and its unlikely to change (although it has changed, like Auriel).
Theres also a few level 11s that I still havent tried since returning which will probably still be in the favorites (Azmo, Gazlowe, Li Li, Uther and STILL my highest win rate hero, Vikings lol) but I still want to put a couple of games into them to see if Im still into those heroes, less we have another Rehgar situation (im still bummed about that).
So im sitting at 21 favorite heroes, these are the ones I will gladly pick up and play at any time, 9 whatevers, the ones that are ok-ish (for me) and I do fine with them I guess but I get nothing out of it, and only 4 that I simply dont want to play.
Biggest surprises so far, easily Nova, Diablo and Jaina who I didnt care for at all 2 years ago, and also Auriel. On the negative side, Rehgar who I used to love, and Kerrigan who... I thought I used to love >_> Also Hammer who i'm putting on my whatever list, her style just doesnt do it for me anymore, or maybe it was just this week's brawl that soured me on her.
