That's a good point and I suppose a big portion of this debate hinges on the difficulty of the upcoming raid tiers in SB.
If we see another Gordias, then I disagree, very strongly infact. Both A3S and A4S required a level of play optimisation that the overwhelming majority wouldn't be able to achieve with either a parser or at the very least, strategies derived from parser data. (And before the 'but muh SSS!', that doesn't teach you how to push DPS on Hand of Pain or burn key points of A4S in time to pull of the wonky strats the majority required to beat it)
If the future consists of Creator grade raids though, then as much as I might appear as a zealot for parsers, I actually agree with you there. Absolute top tier DPS was pretty much optional in Creator from the get go, right from week one either your raid had strong DPS and you can skip a good chunk of mechanics, or you had slower DPS and thus had more mechanics to deal with as a result. Even Zurvan tells the same tale, it's a shame it wasn't quite tuned right and that people promptly lost their minds over it.
