"Actually, it's time to cut Armor out of the game completely."
You won't appreciate every element of the game unless you play all ship types. Some of us do. You seem like the type that plays subs 90% of the time.
While I dislike sub gameplay, it's not because they're underpowered. You're right, their survivability sucks. But if survivability was improved, they'd have to suffer a significant loss in effectiveness. I'd like to see subs behave more like their real life counterparts. Slow stalkers playing a support role. Unable to even remotely keep up with capital ships underwater or even on the surface. But devastating with one good torpedo attack.
If things were my way, you'd have to position yourself and wait for a target to cross your path. Not ram your way into their battle line and cause chaos. You missed? Tough luck. You'd be able to stay under much longer, but when all other surface ships on your team die, the battle ends automatically. Hedgehogs would be less effective and DD's would have a much bigger role whilst getting a big xp reward for sinking a sub with DC's.
Back to the armor dispute. Your sub is your baby. Our BB's and CV's are ours. But the BB's and CV's were here long before the subs were. BB's and CV's can dramitically change their setup to meet the needs of the players unique play style. We want to keep it that way. It's the reason many of us still play this game.
