I think they are needed, but saying that I think they needed to add something like get +1 green die if attacking out of arc or something along those lines. AT are great, but they are limited in what can take them. Turrets like Dash fly around the board with their good dial, shooting at anything they want.
I am of the opinion that big ships' dials are too good generally.
I think FFG does very well with this game but I have to agree that some of the newer large ship are way to good on the dial end.
