As many whom have upgraded guild castle buildings/towers to high level know... It costs an arm and leg to get all of the buildings/towers to high level even with these lovely material sales such as the one we have this weekend.
I am proposing an adjustment to the buff values you receive from the Tower Of Invincible Attack, Tower Of Perfect Defense, and Tower Of Magic Protection. Was thinking maybe add % value at level 7 and up.
Curious what others opinion on this is.
