There are plenty of ways to politely engage a company with your opinion.
People who don't like submarines are very vocal. This is not unusual - when people are happy, they tend not to make much noise about it - they just go about being content and happy.
When people are angry - they tend to make it extremely clear to as many people that they're angry. You will hear displeasure far more than you hear pleasure.
We have conducted a variety of research into whether or not submarines would be a good addition to our game and the results supported it. We don't share those results publicly because it's not normal for a company to do stuff like that. We make our decisions, and we hope that if some players don't like it, that it's something they can at least accommodate into the game experience.
