Capitals aren't useless because they can still be used to escalate the fleet fights. They just aren't needed for structure bashing, which actually frees them up more for fleet fighting since they aren't burnt out from weeks of structure bashing.

SC and Titans are not a good counter to Dreads and Carriers?

Dont compare 100 Dreads to a single Titan or SC, compare close to equal numbers. Dropping 10x Dreads on a few Titans or SC does not mean its badly balanced, but when you need a very clear number advantage to even consider dropping them we can assume the capital power chain goes like this: Carrier < Dreadnought < SC/Titan < Dreadnought blob < SC/Titan blob

If you can field a large enough dreadnough fleet do that, fielding a large enough titan/sc fleet takes alot less people + they can get repaired by other ships (triage carrier out of range from enemy dread fleet will do wonders for SC/Titan survivability)

You mean like the recent S2N super losses that came from an escalating fleet fight that went all the way up to titans being dropped? That was a 'smaller' spread out fight that moved across multiple systems with capitals & supers both using gates and jump engines for mobility.
Seems to me plenty of cap use will still occur as long as the sub cap meta allows escalation to BS's, since then caps naturally play in the chain of escalation.

I'd allow caps and supers to be built anywhere.

I'd allow them to use hi-sec gates.

I'd give all caps t2 modules, guns and drones. Maybe some new faction stuff too.

Capital incursions.

I'd uncouple the need to use a jumpdrive with a cyno and allow caps to jump themselves.

I'd toy with the idea of deleting jump fatigue.

I'd add the following 2 role bonus to each sub cap:
1) "This ship does reduced damage to capital class vessels"
2) "This ship cannot target super capital vessels"

I'd then expand the capital class hull range so it resembles the sub cap range. minimum 3 t1 hulls per ship type, t2 versions and flavors, tech 3 capitals and modular caps.

I'd give new dreadnaught hulls mid slot based anti-sub cap weapons that are great against fast moving, high transversal sub caps in groups.

I'd give new carrier hulls turrets / missile slots to give them more teeth against caps and supers.

I'd give capital ships capital e-war that could effect supers (thus forcing sub caps to keep capitals around in a fight to counter supers, even if fozzysov). I'd prevent sub capital e-war from doing anything to a super (i.e the HIC, which I'd replace with a capital HIC).

I'd reintroduce skynet. No game data needed to justify fixing crap game re-design.

I'd also bring back the AoE doomsday as a T2 module, with a reduced range / AoE. Because you know, each blob of ishtars blapped every few seconds, will fix our Tidi forum tear woes.
