Greetings. From my observation, currently not many people know about crucible, or how to access community-made maps and the editor. I believe the major issues are these:
- The crucible tab in the coliseum menu doesn't appear unless you've already accepted the crucible ToS.
- Crucible ToS is hidden within the advanced game settings.
- The crucible tab doesn't have a button to open the editor, it must be done exclusively within the wrench icon button in the bottom left menu of the screen, and look for it.
- The editor doesn't have a Help button, to at least show the controls or even better, open the Crucible wiki page to teach a few things.

Basically, it's pretty unintuitive. So here are some suggestions to make Crucible more accessible to the average player:
- Show the crucible tab within the coliseum menu at all times.
- The crucible ToS is shown in the crucible tab, which goes away once accepted. To the people who want to see it again/opt out, add a button that shows it. Maybe to avoid spamming buttons all over the UI, there could be a new dropdown button with several options in it, keeping the UI clean.
- A button to open the editor within the crucible tab. Basically all in one place, rather than all over the place.
- Help button in the Crucible Editor, showing the controls or opening the crucible Wiki page.

Public tests can be used both for testing and as custom lobbies, waiting for people to join. It's currently all handled through the Spectate menu, which mixes lobbies that people can join with ongoing games.
I'd like the suggest a new tab showing public tests with players currently waiting in the lobby, so matches you can join, which ofc gets moved to the Spectate menu once the match starts. Basically a "match finder", a "server browser" type of thing, simply separating joinable matches from the ongoing ones.
This would help with people testing maps, as not everyone can find people to do it with or wants to organize events for it. It would also satisfy people who wants to host "custom matches" and just sit there, waiting for people to join, so without the purpose of testing.
