And? These affect you how? They are a piece of land you don't get to steal from. Who cares? That doesn't affect Herocraft as a whole and treating these plots like they are more than what they are is doing more harm than good.
Would you prefer to have a limit on how many chests can be store? (after a week or so of starting your building the chests exceeding the limit need to be removed or the person pays a fee to keep them or add new ones) Or limit amount of people allowed to have perms to the plot?
Or an option to have a chest shop as long as the owner pays a tax and fee for it that may be more expensive than normal shops in the trade district?
The people who can afford plots, already have spaces to put items.
So you still can't raid or steal from them, okay? Find something else to do. Can't kill them at spawn? Bounties, or better yet, find something else to do.
The difference between a Noble Plot and a properly protected Res or Town is the location.
Don't want it, don't get one. Don't like that it's more free storage for those who can afford the 20k or more plots? Well chances are you couldn't get their items anyways. So what's the difference between a nice space at spawn for something to be built onto it for everyone to easily see and enjoy, and a personal Residence right outside spawn? Or a township that's properly protected? Nothing.
If you want Herocraft to be more Hardcore, there is a suggestions thread for that. Don't complain about having less PvP if you aren't willing to find ways to encourage more healthy PvP. PvE isn't what is killing the server, it's players who refuse to find ways to encourage PvP to be better.
I would use it over complaining about an expensive piece of land some people want to have and have earned the right to have.
