The ninjas do have an iteraction. They lose 1 max health for every ally ninja on their team. Leona does 1 less damage to all champion with eye cover (sun glasses, masks, etc) this counts for skins too.

I'd really like it if Tango Twisted Fate and Eve would tango together if they both did a /d next to each other.
