I usually like two archetypes, glass cannons and spell casters. So, in RPG's I'm usually the spellcaster and usually the one that does the most damage, even if it is at the expense of other stats. IN MOBAs/Hero Brawlers I usually play int support or AD carry/agility carry. However, Heroes is a special case for me because, unlike with LoL or Dota 2, I actually like and have some sort of attachement to the characters.
Having said all that, the heroes I'm most excited to play are
-Jaina
-Sylvanas
-Nova
-Thrall
-Valla
-Tyrande
-Zul'Jin
