I like where your going with that maybe it could be worked out so it would encourage guilds to stay together rather than continually recycle every 1k hours. I have an idea that would go along with this.

I know time and time again I have been vehemently against player owned shops,but what about guild owned shops? How it would work: each guild would have its own bank or Guild funds they would use to buy stuff for the guild. You would earn guild funds for every hour your guild holds a tower you get a set amount of gralats say 1hr=100 gralats. Then once your guild accumulates enough gralats (say 10k which would = 1k hours you would be able to purchase a shop that would be available inside the guild house. Players would be able to access it by clicking on your guild and then clicking the enter gh option.

What would be inside the shop? The normal custom milestone reward stuff you would be able to get in a guild. Once you purchase your gh (when you reach 1k) it would come with one hat stand. The selected 25 members would still get the custom 1k hat for free. The kicker is that the hat would be placed on a table or hat stand and be available for purchase to the public. All guild shop items would have to have a set price depending on item type and every time an item is purchased from a guild shop a portion of the profit would go into the guild fund (say 10%).

There would need to be a shop somewhere where you can purchase stands or basically give the ability for gh's to sell more items or item types. For example: 100k gralats or 1k hours you could buy custom hat slots,and 1 million gralats or 10k hours you could get custom mount slots 2.5-5m for 2p mount,and there would be room for other custom type stuff to be added in the future. An option would also be on furniture items in shops to select them for personal inventory or gh inventory so they can be used to decorate gh and shops. Gh furniture would only be able to be purchased by guild owner and would come directly out of the guild's accumulate funds.

So the rewards system would be changed a bit but players would still get a free custom items if they contribute enough. No personal gralats would be gained as it just wouldn't work as there is no current way to gauge how long a player is active on a guild tag. The one major thing is I'm not sure how to start out the system and work around the guilds that all ready have hours?
I think it would be best to start all guilds out evenly and not keep guilds closing in on milestones from getting the rewards.

I would like any input you guys have on that or on my idea in general. I'm sure a lot will not like the idea because it would lesson the value of a milestone reward item if everybody can just purchase it. However I think it would help to off set that if the GH store items where set at higher prices than your normal shops on the map as it should be imo. I'm not sure where to set the price point or range for it maybe 20-30k for a hat and 40-60k for a mount. Idk I want it high but reasonable and not outrageous.
