Basically, I think the way adventures travel right now, is in conflict with the idea everyone should be able to play BM at their own pace. Hear me out.
Advy travel is great. The time-pool, the instant travelling, ... But there's one thing that bothers me: having to wait for your timepool to fill up to a certain level before you are able to make your move. I can imagine, for people who only log-in once a day, how it's annoying to see many of your hours go to waste.
E.g.: Let's say you're in Keplerville and want to go to Kepler. The voyage takes 12 hours to complete. When you log in, you only have 10 hours in your time-pool. If you can only manageto log-in again 12 hours later, you will find your advy sitting in Keplerville with 16 hours (and 8 hours have gone to waste).
But what if you would allow non-instant travelling for adventurers as well? This would mean you invest your 10 hours in the trajectory, and for 2 hours your status changes to 'travelling'. If you log in 12 hours later, you will have completed the journey with 10 hours in your time-pool.
Basically, this system is already in place for long-distance travels, like when a route takes more than 16 hours to complete. All I propose is to lift that restriction, and always allow it.
Priority: rather low. In fact I might be the only person bothered by this? But then again, it seems this only needs a minor adjustment to work, with the benefit of making the game more light-weight, accessible and fun.
