Rationale
Even the API refers to team as family (e.g. the GETMYFAMILYNAME() LUA function), together with several aspects: Your characters live under the same roof and have the same ‘surname’.
Proposed changes
- Rename all mentions of ‘team’ to ‘family’;
- Make all non-untradeable items freely tradeable between family members;
- Rename untradeable items to ‘Family Heirloom’; only allow these to be exchanged between family members.
This reply seems to partially cover this proposal already:
