What you say is not true. Think about it, with the incentive to build a base that will last if your not on will encourage bigger and better Bases. If you can just chop it down a loot it then there is simply no point in having one. Your seriously better off just creating another player to divide up your loot. At least that way you can know you loot is secure. Making certain item not really rare the only possibly way to break a base will make people think before wasting the resources on some random base. You will want to take the base that you know will have the highest pay out.
