Good morning,
First, i getFriends, so i can create a window of firends. When i click on a friend, im going to do, the usual actions, as invite that friend to a group.
The fun part, is that i have to make GetPlayerProfile for that player to get the playerId(Title), because InvitePlayer requests an entity, that only admits character_id or title_player_id.
As long as there are some requests, that asks for master_id and title_id, why do not retrieve both when getting friends? It will improve the performance
