If turrets hit on a 3+, what would happen if natural bombers rolled D6 and fighta-bommas rolled D3?
D6 is an average 3.5 attacks average each - that's more than double the current 5/3 attacks each.
I mean how would it affect on a more strategic level since 3+ turrets would let you shoot down more bombers than normal. So say a 4 bomber wave vs 2 turret ship using original rules vs your proposal vs what would happen if it was D6 and D3 for bombers and fighta bommas respectively?
D3 for Fighta Bombers would be the same as Bombers under my proposed - 106% effectiveness for a wave of 4, 114% for a wave of 8, 120% for a wave of infinite.
D6 for Bombers would be 186% effectiveness for a wave of 4, 200% for a wave of 8, or 210% for a wave of infinite.
D6 without turret really is too powerful to contemplate.
I do think D3 is within the realms of acceptability, especially given the negating effects of increased effectiveness of turrets (which carries over to turret massing), increased effectiveness of fighters, reduced incentive to launch waves of pure bombers, and the ability of turrets to fire at both torps and AC.
So let's put this in perspective:
If all these unquantifiable aspects have a total nerfing effect on AC of just 10% then the net effect will be -4% for a wave of 4 to +4% for a wave of 8. These are negligible deviations from the current ruleset. Am I overstating these effects at 10%? Well launching just 1 escort fighter in a wave of 8 nerfs that wave by 12.5% instantly. The figure is 25% for one escort fighter in a wave of 4. So yes, it is plausible to say that Turrets hitting on 3+ with D3 attacks per bomber and Resilient fighters are no more powerful than the current system.
Does it even unbalance for fleets without a defensive carrier? The increased effectiveness of turrets carries over to turret massing. A T2 ship with 1 supporting vessel will now be 4.2% better protected against a wave of 4 than the same situation at present, whilst with 2 supporting vessels it's just 6% more vulnerable against a wave of 8 than in the same situation at present. These are again negligible differences.
To cap it all off, Battleships are still much better defended than cruisers (being just 50% as vulnerable to waves of 4 or 80% as vulnerable to waves of 8 for a T4 battleship) but not to the point of ridiculousness. This is a far better situation than at present where they're 5 times less vulnerable to a wave of 4 bombers than cruisers are.
Yes, raw bomber output is increased by 20%. But it's not as if that's the only change. The tools to deal with that have been provided. Give 3+ turrets, D3 Bombers and Resilient Fighters a chance.
