Haven clearly has the weakest special ability;
as for Academy and Castle, I don't even know – it seems weak, but also not bad
therefore, what really needs to be done is to either rework "Unrelenting Force" or not make it a special ability, but put it in defense (because this skill enhances "Overwatch," not just direct attack), and put something else in its place as a special ability.
Блистает там воздушностью прогалин.
Но между кедров, полных тишиной,
Расщелина по склону ниспадала.
О, никогда под бледною луной
Так пышен не был тот уют лесной...
