I think it would be neat to have character buffs based on old tales. For instance, Hanzel and Gretel. When they are used on the same team, they supplement each other somehow. Would be really cool and fun to have a backstory based link too.
So when sexy RedSkirt and Wolfy are in the same team they should spread mushrooms and eat any grandma that stays in their path.
This is absolutely hilarious! Well there are other character links! Lol
Something like this has been implemented for Atlantis heroes - they have a ‘family’ link that includes a small buff
