Reimagining Master Missions

Just a silly thought. What if we remove the limit of only 1 master per map, add Tane, Cassia, and the Expedition Crew (4 in 1, fixed rotation) to the list of Masters. Now, you pick your own 4 masters out of the existing 8 masters to accumulate missions for. The rest won't gain missions unless you change your roster on the Atlas tree. Maybe even make it so every map boss guarantees to provide one master mission. This provides a constant feeling of "here's your next quest" so you don't feel like "I ran out of missions, I guess I'm logging off" for people who don't outsource sextants/scarabs.

• Why remove the limit of 1 master? Whenever I run out of Jun missions, I don't bother running other masters because I'm just hoping to find her wild. If we didn't have the limit of 1 master, I would be interacting freely with the other masters.
• Why expand the roster? Because Niko missions sitting there rotting could be put to better use if we had various masters we can pick ourselves. Not having 1 master limit means you can still have Tane Cassia in the same map like before, except now you get to free up one more scarab/sextant slot if you never liked any of the original masters.
• Why Expedition crew? Expedition is popular this league and scarab demand for them is persistent. And if we put them 4 on a fixed rotation, we have one less RNG to worry about. I'm just afraid Expedition is too rewarding of a mechanic to be made so accessible, and I would hate if logbook drop rates are nerfed to compensate.

What do you guys think? Throw in your ideas too. It's just a silly brainstorming session so don't frown too hard.
