@eddiex excuse me, I didn't miss the point at all.
As a generalization, there's two populations at play on the Mud.
A) People that play
as a race to obtain gear and PK
B) People that play to learn new zones and for the value of the community
I'm going to assume that you're in population A, as your solutions are leaning toward a future where no one has gear anymore. This way, you can race to load the best of the best and PK the rest. You're right when you say that Population A gets bored and fickle after about a month and a half, and quickly abandons their interest in Arctic to go play Dota or whatever.
I'll also assume that you're
not a member of population B, as you categorize them as
...players who are not virtuosos so need to grind longer to achieve their in-game goals.
I make it a habit to get fairly well equipped, and then go learn 2-3 new (to me) zones each wipe. I try to really study, map, figure out the quests etc, and starting with the brief notes I have it can take me a long time. There's a lot of folks who flourish during this time, not needing to PK, not especially needing to compete for gear, but rather enjoying the community of their clan and getting to learn new corners of old zones.
If you really want to reinvigorate Population A, consider wiping the gear of anyone that's been rented for more than 10 days. That would keep people from deep renting, and give newly-naked players a goal and purpose (lest they get PKed themselves). Or - maybe - you can only keep gear and coins on (at max) 2 characters at a time (this would keep someone from having 8 fully-geared characters deep renting gear).
Do whatever you want, but recognize that those of us in Population B are pretty active and happy right now.
