After reading about various griefing problems and massive overbuilding of areas, it seems to me that it might be a good feature to have in server settings, where you can limit clans on how many building pieces and placeables can be used.
There could be many factors linked to it. Bigger clans get bigger limits. Higher levels get bigger limits (discourage someone spam adding new alts and deleting them).
Limits could be enabled, disabled and have a slider to determine what those limits are.
If official servers started using the limits, it could help reduce a lot of area lag and possibly prevent clans from trying to block off all the obelisks.
Probably a good idea to do this for pets and thralls too. I had some serious thrall sprawl, but ran around collecting pets and thralls and threw them into about 10 chests. Running around in my bases is much more efficient now. Containers are working better. Seems the more junk I have sprawled around, the more trouble I have getting containers to show their contents.
