Rydr 4 Flak spires almost certainly aren't why novices bring double flak pyras or double mortar pyras. It seems pretty obvious to me they bring them because they see that weapon get the kill and think 'wow that must be awesome, every time we kill a ship it is with that gun, we need MOAR!'. See also hwachaflak galleons. Then they do no damage for the next 5 matches trying to get their awful build to function. Of course when it doesn't work they resort to ramming which makes it suck even worse. This is also likely why they ignore you, they have been conditioned to love the flak (fire gun, enemy dies); their limited experience is telling them you don't know the true power of the mighty light flak.
