Here is an idea for its importance.

Fleets may be formed without a flagship but and use tactics and recieve no penalty etc...
BUT
only flagships carry fleet exp. A fleet without a flagship has 0 exp always. As soon as a flagship joins it gain exp equal to the flagships fleet exp. This represents the fact that it is the flagships commander giving the orders to the fleet and establishing a fleet exp bonus.

This gives good cause to knock out that flagship if it has a high fleet exp.

A limited number I would agree on. I would say base it on the number of ships available. Make it a setting that can be changed when creating a game like the max number of ships to be built etc. Thus different players could have it range across different spectrums. 1 flagship to 1 ship or 1 flagship to 0 ships or 1 flagship to 100 ship or even have it disable for those that dislike em.

Just some ideas.
