at the end of the day, all of this just comes off as mid-tier players squabbling about how "highest tier" play should be when they themselves are .... not good enough to really make that statement. LOL
besides, the variability of gameplay in the higher tiers isn't really the thoughtfulness of the strategy employed, but rather the consistency of it's execution. most people, unless they are grinding out and practicing these combat rotations or group strats at regular and frequent intervals, are going to be making more small mistakes that accumulate and wipe the raid. but to be honest, it's a lot to ask of someone to dedicate so much energy and time into a game unless you're going professional with that game (and i guarantee you there is NO professional scene for this game)
