1. As said, they are streamlining that portion of the MSQ in the coming months. Please look forward to it.
2. If you've unlocked Grand Company Squadrons you can run a lot of dungeons with them (NPCs) and you get instant queues and go at your pace. ShB has the trust system for the same idea but a bit more "efficient" with mechanics etc.

So yea, both your issues are going to be solved or have been solved if you level up and unlock the solutions *Thumbs up* Welcome and good luck!
