Zeren in a seton open seabattle this is difficult. I played vs petric and he used normal cybran scus to built harms. Everytime i used my uef battleships groundfire harms i lost thousends of damage for several seconds. This was deadly. I lost more and more territory on water, after 10-20 min battle i was pushed back to my harbour. THanks god my team lost faster
You need to units to fire the harms and once they are under water it costs you hell mirco time and damage to kill them. If people would remove the possibility to groundfire such units they would be definately op.
