Boost for clan castle require time
Many times when we boost our barracks although our army is trained faster but the clan castle reuire time remains the same which becomes difficult when we r raiding with full cc and require the spell or troops which r essential to our attack r in the cc...
I hope supercell will consider this to boost the required time of clan castle and its advantageous to them too as people will spend more gems meaning more money for them instead of forcing people to spend 30 gems at once on barracks whether u have 6 working barracks or not.
If supercell moderators see this plz reply if its possible or not in future...
