But again - I don't recall seeing any 'rule' set out by the game itself (namely SE created in-game dialogue or messages) which stated "Thou shalt only enter/participate in this content in a premade team".
This was still outside of the forked tower, at the pavilion presumably. Dont get me wrong, the way SE implemented this is bad. But it's bad because it allows for behavior like OP's.
