You wouldn’t want battleships with capitals weapons for a few reasons.
-
Battleships can get fairly large EHP and get reps, you don’t want a fleet of 500 anti-capital battleships that can wreck a fleet of capitals and possibly subcaps (like BC’s or other BS, which can already be done by LR Titans/Dreads).
-
Battleships retain their mobility unlike a seiged dread and are faster than a Titan. Plus they can MJD, which can make it difficult to pin them down as they take apart your capitals.
-
Capital guns have long range, they can use this range to compensate for their poor tracking (again, LR Titan/Dreads can hit sub caps already).
There could be some counters like using frigates, but again, it comes back to them having BS sized tanks that can be logi’d.
In the end, it makes them too strong and not able to be countered easily, which will put us in the same boat we have now with capitals, just switching the ship type.
If you want an actual anti-capital subcap, arguably it would be better to make either a T2 or T3 Attack Battlecruiser.
Let it continue to use battleships sized guns, but give it either a high slot module (or a mode if T3, like T3D’s), that when activated, increase damage to the 2000-2500 dps range, but lower tracking by 99% (or equivalent of capital tracking, with other possible modifiers such as decreasing speed and possibly decreasing signature so capitals can’t apply as well).
This changes the fleet dynamic. As, ABC’s by default are squishy, even if T2 or T3, i wouldn’t expect to see their EHP higher than 70-80k. This means a fleet of Ferox can just erase them as a hard counter, and T1 ferox countering a T2 or T3 ship, will trade well in the isk war department.
With them being battleship sized weapons, they are now range limited the same as battleships. Which means a sniper ferox can out range them, and it also means they can’t just go to 250km with LR capital weapons and track everything, since they most likely won’t be range bonused.
This means that the “Anti-Capital” ABC would be something in the 50-60km range, doing a lot of damage as a glass cannon, but can be countered easily by other subcaps or bombs, but will be big damage dealers against capitals. If supported properly, they can bring down capitals with ease, but when another subcap fleet lands on grid, they are then countered.
