Even if it was a single source, perhaps it would simply be better if it were per character per planet?
Due to the nature of having multiple people living in a town, and having to collect footfall from more than one source (for a guild mind you, not for me personally), it is a bit of a chore to have to visit the half a dozen or so beacons spread out across the city (infrastructure) and would be nice to collect from one place instead.
That being said, I don’t see us getting this QoL because it would likely break more than it fixes. for instance, if you fuel from one place, how many beacon fuel items will it take? 1 to fuel all 20 beacons? 20 to fuel just one of them? how does it know which ones to fuel if you spread it out? Personally I find gleam club to be a more reasonable service because it keeps all my beacons fueled. I want to support my MMO and it is not a high fee for a 6 month stent of knowing all the beacons are safe.
