I would recommend a item that can be directly connected to the tc that will allow it to hold more resources. What i had in mind was a box that you could place and it will be like a box but you fill it with resources and it will give you more time on tc. The reason I think this would be a good idea is because I think if you can afford it do it. This will benefit a lot players, not only clans but smaller groups and solos, the reason i say solos is because they can build bigger bases to protect more of their loot, most people can find people to play with so if they cant keep up with the base they built then get a friend on or find a person to play with that you know you can trust. if you think this only applies to clans use a open mind and think about all the benefits this will have for smaller groups.
