So what is the point of having fighter class on every nation? 

You still are able to choose the other modes including fighters. Right? And some ppl like fighters. 

Well thats just crazy!  Battleships would have to carry scouts AND AA guns !!

You do realise that the main issue between bb and cv is that cv don't use fighters to cover them and provide sight. So absolutely this would solve this by having no bb in the game room. It's a bit like removing asw to counter ss complaints.

I think it's a good idea ... players who don't like teamplay (helping BB's by using fighters) should play in separate room - room for bombewhores ... only those from old school (those who like provide fighter cover) will stay in current GB rooms ... everyone will be happy - those who like bombing will have their room, those who like fighters will concentrate only on dogfights/providing view, bb players will worry less about bombers and fog of war ... the problem would not exist if SDE have given the same amount of exp/credit for bombing and shooting planes from the beginning ... :P
