Lol, the scout spam. God I love it. I started the Amish revolution
Anyway, the Dunov Idea is a good one, but it only works to an extent. In an online game, getting two, MAYBE three would be ok, but in online games, you need a fleet. Plain and simple. Capital ships don't do as much damage as say 6-10 frigates that you could have made instead.
Plus, you have to pay a lot more to get a lot of caps early because of the money you have spend on cap ship slots.
Cap ships aren't meant to be "spammed". They're meant to support. To be the bastion in the fleet representing and supporting your method.
Two dunov's is ideal because they can shield regen each other and any other cap you have. Three would just help that concept. In online games, however, you will probably be rushed too quickly to ever have a chance to get more than 2.
