I’ve discussed it before in a different thread, so i’ll try to summarize.
My original thought would be to just add 1AU to all ships in the game. This moves BS up to 3AU, cruisers up to 4AU etc. There would be no difference in how ships interact (you could still catch BS with cruisers, inties would still be the fastest kids in town, etc), but you’d gain a huge quality of life improvement as far as travel times go. It also improves how hyperspatial rigs interact, as 1 hyper rig would put you right dead on with BC’s.
2.2 AU would negligible but not something i’d opposed. Its still a gain. The main problem with BS warping is that its the deceleration that is a problem, not the actual warp speed. You sit “decelerating” for 5-7 seconds, on grid and cannot lock/target anything. 2.2AU does not change enough of how that deceleration comes into play. 3AU/s would effectively make BS come out warp similar to cruisers, and cruisers come out of warp, similar to destroyers. This is where the biggest change/QoL comes in, not necessarily time spent in warp.
All that being said, i’m not too concerned about BS warp speed, i’d rather CCP focus on sig resolution and sensor strength, that would have a larger effect on making BS more lively on the battlefield instead of feeling like they’re gimped in all areas. A fair number of BS have sig res that is less or equal to dreadnoughts and carriers. There is nothing more boring/frustrating than waiting 20s to lock a frigate that has you tackled, only to have him warp away by the time you finally get a lock. Or when you’re jammed and break the jam, only to wait another 20s to try to lock something and then get jammed again.
At this point, carriers and dread’s have the lock time advantage against battleships, which is just backwards and dumb. A battleship can barely even lock a carrier’s fighters before it gets volleyed off the field (unless ofc you have logi and are brick tanked, but thats a separate scenario).
I think a niche exists for BS where they would have stronger sensors, making them slightly more effective at countering EWAR (targeting range buff has already made somewhat more resistant to damps). Increase sig res by 25mm across the board (maybe 30-35 for the Rokh and SNI), and then increase all t1 BS to current navy faction BS sensor strength and add +6 to all navy faction BS.
