For example, a player playing 'Thor' when making a titan will summon a 'Thor' unit/hero, rather than a gigantic Troll. The Unit doesn't even have to be huge, but can have great stats like a watered down Arkantos (God). I always thought the Titans themselves were a bit lame looking.
Norse mythology is really big right now (MCU, God of war, Vikings.. etc) would be nice to have an actual Thor, Loki and Odin character/unit in the gameplay. Would probably attract new players.
