A mixed bag, but at least notable for its candor. They seem determined to ram subs down our throats no matter how unpopular they are, sadly. They learned nothing from CVs.
But at least they worked hard to polish this turd and at least they were open about it.
Note that they removed the damage bonus.
To address this issue, while also preserving the unique gameplay we've built for submarines, we've reworked their torpedoes, splitting them into two types that will receive different bonuses from their use in conjunction with sonar pings.
The first type are homing torpedoes. Their maneuverability will be reduced, and the distance at which they stop homing on destroyers and cruisers will be increased twofold. The rest of the parameters and mechanics of these torpedoes remain similar to the current ones on the live server: the first ping activates homing, the second ping improves it, but doesn't make it better than how it is now on the main server. However, the successfully Sonar Pinged torpedoes no longer receive any bonus to their damage.
The second type are torpedoes with a magnetic detonator. Their base damage is somewhat higher than that of homing torpedoes. The first ping reduces the torpedoes' detectability by 25%, and the second ping doubles their damage if they hit the torpedo protection. These torpedoes can potentially deal a lot of damage, but they do not have any horizontal homing at all — when the Ping effect is active, they can only ascend or descend to match the level of the target.
