While I 100% agree that battleships are very weak at the moment, I’m not sure about these. They all feel like waaaay too much.
Rather than go through each of them (I’m lazy) lets look at the Caldari bonuses.
The Scorp getting a 75% role bonus would turn it into an utterly extraordinary ECM boat. Easily best-in-class, even over the Rook and Widow (even giving the Falcon a run for its money). For example, a flavoured ECM II with no SDAs and a single dispersion aug II would have a jam strength of 15.6… without heat. The widow, a Tech2 battleship that also has ECM bonuses, sits at 12.9 with the same fit (no SDAs, one T2 rig).
But the real icing on the cake is the price. They’re so utterly cheap that after insurance you can whelp those allllll day. With a full mid rack of ECMs.
The Raven’s bonuses collide with the Bagel and the RNI. Those bonuses are significant for a reason. They’re also on pirate/navy boats because of their significance.
Rokh makes an excellent sniper boat. These will just become alpha doctrines, which is in direct conflict with artillery boats. Interestingly, the proposed RNI bonus would have been much better for the Rokh. All in all, not outrageous, but still too much.
The navy scorp… it’s tanky (personally, where I think all battleship tanks should be at, with the SNI over and above where it is now). Giving it tank AND spank without taking something else away is having your cake and eating it too.
And the RNI. I can’t possibly see how this would benefit it outside of PVE. Even bonused, the cruise and torp bonuses make it useless fighting anything smaller than a cruiser (even then…). Stuff >=cruiser size doesn’t take long to lock. If you’re far enough away for a range script to be useful, you’ll just get probed down and warped onto. Best case, they become yet another sniper boat.
All in all, the bonuses you propose are all the same. They don’t taste right, they don’t really fit the problem.
What is the problem? Depends who you ask.
Honestly, give them a much higher warp speed (mach getting to double-dip of course) and give them probably 50% more ehp via raw stat boosts.
They’re supposed to be tanky ships that slug it out. 50% more ehp would do absolute wonders for breaking alpha fleets. And the warp speed would mean you wuoldn’t slit your wrists for even thinking about flying them 20+ jumps.
