Warehouse
With this you could have different levels of warhorse which have different troop numbers when you take it and can allow more resources inside
Here's what I thought:
Level 1 warehouse - 100000 of each resource
Level 2 warehouse - 200000 of each resource
Level 3 warehouse - 300000 of each resource
Level 4 warehouse - 400000 of each resource
Level 5 warehouse - 500000 of each resource
Level 6 warehouse - 600000 of each resource
Level 7 warehouse - 700000 of each resource
Level 8 warehouse - 800000 of each resource
Level 9 warehouse - 900000 of each resource
Level 10 warehouse - ???? Of each resource
And I think if each warehouse has the same amount of troops as an oasis it will give all ranges of players a chance to get a good warehouse.
Note: the level 10 warehouse could be a mystery and is rare to find such as a level 10 oasis
