Lots of new ships have been added to the small ship classes in the past several years, but not much for bigger ships. We have had T3Ds, Command dessies, EWAR faction frigates and the endurance. Not to mention recent buffs to AF and HACs.
It appears a niche could be had for battleships with ewar applications (albeit, in limited application so as not to feel too overpowered or make dedicated EWAR less effecitve).
There are already 2 EWAR battleships in the T1 line, the scorpion and armageddon. So we could add or repurpose 2 more T1 EWAR battleships for minmatar and gallente. Or we repurpose the existing T1 EWAR battleships to full combat ships and create faction EWAR battleship line (like the faction EWAR figates).
Option 1
If we repurpose existing T1 battleships, the typhoon could drop the explosion velocity bonus in favor of a targeting painting bonus (which would help in application of all missiles, not just torps/cruise like its current bonus).
Gallente is a little more troublesome, as the mega and domi are effective with their bonuses. The best fit would be the domi, as it has more mids and doesnt risk as much application loss since it relies on drones. It would gain a disruptor/scram range increase.
Why TP and Disruptor/scram bonuses?
We dont need more long range webs, we have the bhaal for that anyway. Battleships suffer from application issues with their larger weapons, a TP bonus lets both guns and missiles apply very well. Its like a super tracking computer for guns, as sig radius increase = easier tracking.
As for disruptor/scram range, BS scan res is too poor to try and lock another ship to properly implement damps, esp if its another EWAR ship, or to switch targets quickly. Scram/disruptor bonuses would help allow the slow domi potentially catch faster ships and extends its tackle range so drones can chew people up. We could consider rolling the drone optimal or tracking bonuses from the replaced trait into the 10% damage/Hp bonus.
Option 2
The second option would be to convert the geddon and scorpion into fully fleshed out attack ships. Then make the Scorp navy, geddon navy, domi navy and typhoon navy into combat EWAR ships, similar to the faction EWAR frigs, but without the penalty.
They would have 2 traditional combat traits like they do now but with a role bonus to their respective EWAR.
Typhoon FI = 25% bonus to target painter effectiveness
Domi NI = 50% bonus to scram/disruptor range
Scorpion Navy issue = 75% bonus to ECM and ECM Burst jammer strength
Armageddon NI = 50% nuetralizer optimal range and 25% falloff bonus
This keeps the original EWAR bonuses from t1 hulls (scorp loses range admittedly) and for the typhoon and domi, they are half of what dedicated EWAR ships provide. Still a nice bonus, but not causing dedicated EWAR ships to be obsolete. There may be some wiggle room to increase the TP and disruptor/scram bonuses, but figured we could start conservatively.
This would also create some demand in the amarr/gallente FW LP stores, as amarr seems to have fewer high volume items.
Obviously the new navy geddon would have higher EHP, cap and slots than T1.
Option 3
Add 2 new T1 EWAR battleships to gal/minmatar and 2 new T1 combat battleships for amarr/caldari. This honestly feels more clumsy and might mean CCP needs to create new hulls and balance 4 new ships, instead of repurposing existing ships.
