would a significant amount of dmg be lost from 1 tac console at max level?

they are something like 30% dmg to xxx dmg type. so, for instance, the difference between a full cannon setup on either a fleet patrol which has 1 less tac console compared to a fleet tactical retro which has 5xtac consoles.

is the wasted ensign tac boff in the retro worth the dmg of 1 console?
or... is the ensign eng in the patrol worth the added survivability?

5tac consoles and wasted ensign in full cannon build

or

4tac, extra eng console, extra eng ensign

this is of course assuming no torps, no beams and alrdy slotting tac team 1 x2 in the other 2 tac boffs.
