Not enough with the battleship guns. Currently the massive cap need for these guns is keeping amarr battleships from being used again. Amarr already suffer from having completely predictable and easy to tank damage types ("they are forming a-hacs? just tank em/thermal, gg we win").

But the battleship guns cap need almost make amarr concepts unviable. I know that a lot of people have always mentioned how the amarr are at a disadvantage because most of their ships are missing a bonus (10% reduction in cap need for guns, where instead they could have a useful bonus like every other ship in every other race). The truth of the matter is, you just can't run an Amarr concept without that bonus, unless you make serious fitting decisions to reduce the cap need of your guns.

The most popular amarr concepts of the past 3 years have been Zealots, Abaddons, and Armageddons. Zealots and Armageddons both get a -10% reduction in cap need for guns, and even then, I can tell you from personal experience that the Armageddon still ran out of cap boosters quite quickly in any fight lasting longer than 5-10 minutes. Then you have the Abaddon, for which the most successful iteration of this concept had to use TWO TECH 2 RIGS just to make the guns cap need managable, and make the ship last more than 5 minutes.

Without the rigs, the Abaddon just eats through cap boosters in 5 minutes or less, turning the abaddon into a small gang ship at best. There are times when the ship would work without the two gun rigs, but usually it was just because alliances or FC's were using it inefficiently and not firing their guns all the time.

The fact of the matter is, there is a huge upswing in cap need for all BS sized modules compared to cruiser sized modules. Look at the difference between a 10mn microwarp drive and 100mn micro warpdrive. The 10mn MWD takes 13.5 cap per second, while the 100mn MWD takes 54.1 cap per second. Most BS get double the cap recharge rate of their cruiser cousins, but many BS modules take 3-5x the amount of cap as cruiser modules.

The main point is, the abaddon shouldn't need two rigs dedicated to reducing their gun's cap need just to last more than 5 minutes in a battle (including cap boosters). It's terribly unbalanced and it's part of the reason people have stopped using hellcats.
