To not slot the maximum number of Energy weapon Tactical consoles that your ship can have? Particularly on escorts.
Back when I started playing early on in the year and right up to when I took a 3 month hiatus, the rule of thumb was for all of your tac consoles to buff your selected energy weapon. But now it seems like a LOT of people are dropping a console or two and slotting Torpedo consoles.
When and why did this start happening? I just don't get it
Because of diminishing returns on the consoles. And because (unless we're talking PvP), the amount of DPS you need to put out in order to do PvE (including Elite STFs) doesn't require more than 3 x whatever Tac Console.
My KDF Sci flys a Peghqu' which has 4 x Tac slots and the DTS console sits in one of them for two reasons:
a) I need both Sci slots for Field Generators as the Peghqu' seems to have paper-thin shields.
b) Plasmonic Leech is a great universal console, particularly for Science builds that are weapons power heavy (as mine is) - so that goes in an Eng slot.
At first I had 4 x Disruptor Induction Coils but was pulling aggro way too much (which my Sci setup wasn't really equipped to deal with) so I sacrificed a Tac slot and have become a good deal more sturdy (and subsequently useful in STFs) since.
Rationales may vary but if you use torps (with say, THY) then sacrificing one energy console that's contributing very little for another that contributes a lot may not be a bad strategy.

I could be wrong but the last time i check the consules do not have a diminishing return. equip one at a time and you will see that each one adds the same amount of damage, and that is baased off of base damage of the weapon being used not he boofed or skills dumped into weapons.
There's no diminishing returns on tactical consoles, they stack as a linear percentage of base weapon damage.
Interesting to know but doesn't change the fact that additional DPS on a single weapon type may be perceived as 'overkill' which in my experience with the Chimera, Peghqu' and Defiant Retrofit in PvE, it almost certainly is.
And let's face it, Tacs get most of their awesome DPS spikes from APA and other skills.
*Edit* I will note as a personal preference though, that if it's viable to slot max Tac consoles I will - in the case of the Sci/Peghqu' it was counter-productive and since the ship is diminished by losing the DTS console, the Tac slots were the only place it could go.
