About Co-operating points: When they are full but in your guild nobody needs improvements or can't afford any, you should have the possibility to bring the points on a kind of "guild bank", and then the points can be used when it is necessary!

There needs to be a way to use mana if all trees are cut! I just don't need the spells anymore in end battle (except for some Ninjas). But why having a full mana bar? ;-)
Wow )))
