This is why I suggested (about 70 pages back) a model where we go back to the old decay formula, but remove the minimum cap, and only count players as active if they have earned renown since the last decay period.
That way no one is "punished" for not logging in, or not stepping into a quest or explorer area, or for having to leave before they do anything of note. That makes decay an honest per-player calculation, and means that only people who are actively earning renown are contributing to decay.
The other idea I proposed was to make amenities purchased with renown directly, so that decay reflects exactly the benefits you're getting from your ship. Giving each amenity a set number of charges would favor small guilds here, and giving them a set time would favor large guilds, and we would certainly get to argue about whichever system they implemented, so it sounds like a win/win to me.
I'd also support the complete removal of decay, but since Turbine decided to put it in, and declined to take it out, we must assume that it serves a purpose, or for some other reason will not go away.
So, slarden, accepting that we would both like to see decay removed, and assuming that won't happen, what is
your suggestion for an alternative system to the one we have now. Because if you're not part of the solution...
you're part of the precipitate.
