The following are Heroes that I think feature mechanics or themes that would be worth exploring in League of Legends:

  • Abathur - Plays the game through proxies; like the Summoner from Dungeon Defenders. Never encountering another champion in person isn't unheard of.
  • Brightwing - Fairy dragon.
  • Cho'Gall - Two players control the same champion.
  • Leoric - Persistent presence while dead and respawns at his current location.
  • Murky - The ability to respawn from a champion summoned unit on a 3 second death timer.
  • Nazeebo - Shaman.
  • Nova - Stealthed roaming assassin.
  • Rexxar - Persistent pet.
  • Sgt. Hammer - Self-lock down to dramatically increase range. Old Xerath and sort of new Kog'Maw.
  • The Lost Vikings - One player controls multiple champions.
  • Zagara - True minion-mancer.
