It’s possible that with full mastery gear and many combinations of azerite, Essences, and talents, I missed the perfect glacial spike build that would have been a different enough sim to think it was better by enough of a margin to play its less appealing to me playstyle.
But the point remains that if it took dozens of sims with high levels of gear for each build, and differences weren’t drastic, then it remains possible that the same will be the case in shadowlands.
Remember that when a meta exists, many people will just follow it rather than trying to make the best version of their own build.
Probably not a ton of regular players out there with full haste crit corruption and numerous azerite combinations to test for themselves vs full set of mastery corruption to see the numbers with their own eyes on their own gear and with their own practice. It’s easier And less frustrating to just chase what has already been proven to be great.
Of course after all that, fire was still a LOT stronger on aoe situations, so I had to give that a go for a while once we got up to 18+ keys.
I just hope shadowlands lets us play what we want without such a drastically clear best option.
