Ok, obviously you're very young, so I'm going to try and help you out with post like this.
1) This should have been posted under wishlist because this is something you wish to be in the game, I'm sure Skuzzy will move it there in the morning.
2) No one is going to listen to you with that kind of sentence structure, grammar, and spelling. No, everything doesn't have to be perfect, this is just a forum, but being able to read it without getting a headache is important.
3) Submarines have been on the wishlist for a long time, I think there are even some relatively current threads of it. You should have searched the forums using the search box in the upper right side of these pages. Then you could read up on some other people's comments for and against this idea.
4) Saying "this game needs submarines!" is not an argument. You need to explain why you feel this "needs" submarines, in what way would they be beneficial, maybe address some of the concerns of others. I don't really know what you are talking about control modes.
So just slow down, read some other posts, and make a clear, understandable, well thought out wish.
