Just a thought to reduce lag as I am assuming 80+ chests in a base would reduce impact on a server vs a clan bank like the guild banks in World of Warcraft.
I like the idea, but we have vaults, and just because the option for a clan bank (and vault) is available (if it was ever added), it doesn’t mean the players wouldn’t spawn 80+ chests on top of that for private stuff.
Diminishing return variable of some kind would introduce a virtual breakpoint in case the mentioned feature becomes a hazard to environment.
