But there's no shared XP there.

Why waste time with a mode that won't give you any XP if you can waste time on a mode that actually gives XP at the cost of random sudden and imposible to avoid deaths due to sub torpedoes?

When I drive my BB, I kill an SS nearly every game. How? I use HH, and the awesome thing since last patch is that I can still use my AA guners for them now, since they got back the "Gun" skill, so no reason not to. Yes, AA can be helpful, but lets be honest, the are MANY AA ships cruising around, and I get sunk by CV way less than SS, so its ASW secondary for me. Here is an idea: Load HH on your ship , set to gradual, 45deg angle and pop on to mark your shell. Now you know where they land. Then play. When you see an SS start to cause problems, pop an HH on it and wait, when it comes out of crit pop another. This also assumes he dives in time. At any point, you will either hit it, or it runs out of air. Then you kill it. NO, you can't totally ignore the SS, but you can kill it, if you take evasie action, you can at least not be killed by it., Too often I see an SS take out 3-4 ship all together cuz they just mill around and ignore the SS. HUH? Dude, until it surfaces, it owns your ass, so run idiots! Lol, not a hard concept to grasp.
SO try that a few times, you will feel VERY happy the first time you melt an unsuspecting SS with a blind shot from your HH. Otherwsie, make yourself look very very foolish by creating a thread like this. Think about it. Even the biggest anti SS people, who have actual reputations and pull with SDE/TNF dont suggest this. It's for a reason.

Denying the entrance of the entire ship class would make it 100% impossible to level up a sub. If you don't like subs, apply Hedgehogs, Depth Charges, or torpedoes to counter them. Submarines have been in GB all this time and the game is still running fine.

Although the solution to starting and playing a game without subs has always existed, somehow we need to extend that concept to the regular room (GB1).

At the end of WWI, the delegates to the Treaty of Versaille, argued that submarines were illegal under the terms and conditions of war. That the use of submarines constituted a capital war crime. Germany was forbidden to have submarines or an air force. The battleship was supreme and Aircraft carriers were only on drafting tables.

Of course, history made mincemeat of those arguments, as both the CV and SS were born and used by all nations, and to this day reign supreme, as the idle Battleships of bygone eras have rusted and become mere museum attractions.

It always amazes me how people somehow want to stop time and deny progress. Not just in a dumb game like Navyfield, but all over the world.

Battleships are obsolete, get a clue.
