Please also note that on larger fleet engagements the attack timer gives time to both attacker and defender to bring in reinforcements.
Some ships may leave while others may come, changing the odds of victory just how it would happen in a real battle.
There still needs to be some way to decrease this timer as well. Perhaps with higher level combat drives. Maybe create a module for for sensor jamming or something. The attack times are just too long at times. Especially when you are attacking a player who is offline. Not to mention reinforcements are either going to need really good engines or already be close by to join in on the battle to help out. In most cases it would just be better for the defender to just jump out. Which they got way too much time to do in sometimes. Too much time to even be realistic.
