Slight problem with having a large fighter escort for cap-ships, LAG.
Even if the other side/group turns up with less ships you'll still get a lot of lag and any missile cruisers/BS's would be useless as they wouldnt be able to fire their missiles (I know this for a fact it's happened to me at least twice) just whatever energy weapons they have.
Plus anyone remember the fight over New Berlin with the -=?=- that resulted in a server crash?
