what about having a guild storage, where guilds can gather resources for events or for helping eachother
a guild storage that can be upgraded through shared efforts of all the members
and maybe where each member can have his own private stash
just like island storage,
- area where only the leader can add and take, and all the users can only add resources
- personal area where only individual users have acces..
- common area where everyone has acces
all upgradable through either shared or individual effort
