Be a "Part of the Team" skins.
I'm not sure if you guys @ Riot have already thought of this. But in light of the recently featured video about how LoL is a TEAM-based game, I think it would be within this spirit to create more matching skins for a team. Look at Battlecast Cho'Gath and Urgot for example. Now imagine an entire team.
This would:
- give teams a slight psychological advantage (intimidation) which will prompt other serious players/teams to follow suit.
- help bolster the comradery of the team members.
- create a more professional atmosphere for an eSport game.
- spark more interest for skins and LoL in general and help to promote a healthy player community.
I hope others agree with me. But that's what we're going to figure out on this forum.
