Legitimate question here.
Everywhere in these parts, we see how <insert_job> is weak or how people always find and use only the best path...

If that is so, why do we see so much different setups in videos ?

At Savage release, everyone jumped the bandwagons "PLD sucks", "MCH is garbage", "AST is dumb", etc...
Yet, it's not uncommon to see clear videos with approximately any job as soon as early september, when A4S world first was only 23rd of August.

If that's the case, isn't it just saying that people are still basically playing what they want and not automatically reroll towards "What is best" ?

Maybe people still think playing the game is...for fun.

By the way, in one of those A3S clear videos, one PLD had over 19k HP, so he probably had some vitality on its right side, too
