Aren't both teams supposed to have dds to counter the enemy dds? or radars? aren't dds trading hps to scout and cap? where is the skill battle between the cv player and the dd player if one just has to pass over the other to scout her (and if he can damage her) making the dd taking damages, forcing her to back off, giving space and hp advantage to your in case of a future knifefight (because focus dds and save yours win games), u might lose some planes or even the entire squad depending on the situation/ship ur facing but, dude, planes are ammo, dds hps are not. As simple as that.
Peace
