The reason i suggest something like this is to stop what ive seen as capital ship spam. Not necessarily on part of players, but on part of the AI. they spam flagships at you like the pirates spam raiders.

Well its really not that good of a strategy. Only reason you might see that in the Beta is because Capitalships are the only things that can stay in a titan battle for a little while, and their abilities are great support in this situation. Fleets die far too easily when fighting titans, and just end up giving your enemies XP (which you want to avoid at all cost). Thus capitalships are the best unit to use to support your titan against an enemy one.
If titans are later balanced so that certain frigates can at least hold their own with titans, this tactic will probably disappear, since per fleet supply capitalships have horrible stats, and having to many of them automatically punishes the player due to the fact that they split XP among each other, diluting their strength in the long run.
