Friend Management

[HeathNaylor]

• [x] Add friend by case-insensitive summoner name
• [x] Remove existing friends
• [ ] Add friends table to ERD
• [ ] Leave flexibility to operate with Teams to suggest friends

[Cisco89]

• We decided to implement a pivot table, since we are not allowed to call upon friends list trough riot API
• Cannot obtain information on teams in the API at this moment therefore, cannot suggest friends
