In another thread a user mentioned that they have an elite and doctrine loadout they swap to in response to seeing their opponent run stacked tactical marine doctrines.
My experience, based on perhaps more forgiving modes like 2v2 and 3v3, was that players all tend to go with their preferred loadout with little to no swapping in/out of alternate elites or doctrines. But as I understand it, the intent of the 60 second delay for QM matches was to allow players to change what they have equipped based on their enemy, so I'm interested to hear situations where this is how it plays out.
What is your "standard" loadout, and what do you change about it depending on what the opponent is fielding? Do you account for specific elites or doctrines, or factions?
