cvs are fun and speed up combat. so +1.

CVs speed up combat indeed, just look how fast bombers and JABOs come in after the position has been revealed to the enemy.
I have no complaints about CVs being sunk to the bomber pilots or person in command of the task group, often no effort is made to defend them. Person in command is frequently doing something else and then just randomly turning the boat. I don`t command the task group often, but when doing so then I enjoy the high-stakes game with the bomber pilot who has taken time to fly low and slow to attack.
