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
