Kneejerk reaction to PLD changes.

That would fall under niche strats. It’s not like in SB where cover could be used on the MT in place of a swap, basically allowing PLD to use cover in any and every fight where there would be a tank swap. Now, you can only use it in certain fights in certain situations. Like covering puddles in T13, or covering a ranged in O11s, that’s two fights over the course of 3 expansions where cover is used on someone other than the MT, definition of niche.

Um, the first half of seiryu EX fight and some latter where you need to tank swap because of cursekeeper debuff. PLD can use cover here to take away cursekeeper from MT and then break off the cover line while still able to DPS which help reduce tank swap.
Another is O11S JP strat for omega when the 2nd mustard bomb hits MT because of cover mitigation the PLD here is able to survive. I don't know what NA/EU strats are but in JP PLD here pretty much use cover extensively.
