Thank you for creating a feedback thread. Naval game mechanics are my hype area so I’ll write best I can.
Bluewater Hull Flooding
Currently, we have a system for flooding which simulates percentage of buoyancy lost, in which each compartment is assigned a total percentage of buoyancy. When fully flooded, if the value of any combination of these compartments adds up to 100%, you sink. In my opinion, all that needed to be done was to standardize these percentage values to be consistent across classes or types of ships, and display the values in the hangar.
If you’d like to remove the unrepairable breach mechanic and replace it with this new system, then why not have each destroyed compartment remove a percentage of the ships buoyancy rather than require a flat number of compartments to sink?
Finally, I’ve noticed that there was a reduction in the total HP of hull sections. Every bluewater ship as far as I can tell, now has almost exactly 20% weaker hull sections. As stated by others, I fear that this will create an environment in which rate of fire is lauded even more than it already is - which is saying a lot! The good old 5"/38 would have a field day, and the SKR would once again reclaim the throne. That thing is already great at destroying hull sections in the current system.
Coastal Cumulative Hullbreak
This is obviously designed to prevent bow-tanking which has been both a blessing and an annoyance since the start of naval forces, depending on the vessel. To use an extreme example, it’s currently possible on the live server for a G-5 torpedo boat to survive several 76mm or even 88mm hits to the bow, since each of these shells aren’t large enough to trigger a hullbreak individually. I agree this is ridiculous for a vessel of this size and construction.
However, having no limit as to what caliber weapons can cause a cumulative hullbreak is very dangerous. Just as with the new bluewater flooding mechanics, this greatly incentivizes extremely fast guns and sometimes eliminates the strategic need to flank the enemy. Craft with CIWS or L70 Bofors already dominate, and this would make them even more powerful - especially when you consider the Pr.206 and Saetta aren’t affected by the new hullbreak yet. Given that the bridge is considered one of the modules which can trigger this new mechanic, it’s theoretically possible to break the keel of any boat by firing enough 7.7mm rounds into the helm!
Finally, I would like to point out that it is currently applied to coastal vessels unevenly on the dev server. For example, a reserve torpedo boat can sink from cumulative hullbreak, but larger vessels - even those heavy boats using the simplified damage model - cannot be broken. LCS, Asheville, MPK122 - these are all immune. If the mechanic is to stay, there needs to be a standard.
