My suggestion is:
> Upgrading future buildings to lvl 7 with titanium bars and other high end resources.
> Some of the Future buildings should be constructed with titanium bars and another high end resources.
Why is that?
> i think the titanium bars are still not use at the HIGH END value of how it should be used.
I apreciate that:
> Castle use titanium bar to be upgraded to lvl 6.
> Used in events
> You can use them for Damasc Sword and Crossbow.
