Which Tier is your favorite to play?

[Cosi]

But parties built to different power tiers do play differently:

Well, yes, you'll note that I totally acknowledged that you do need to scale challenges to different characters. But that's not "Wizards are inherently broken". And, frankly, Wizards don't really trivialize normal play outside of a very small number of broken spells. Different characters have different power levels, but the specific way the Tiers describe those power levels is stupid. Yes, Wizards behave differently from Fighters. But using the Tiers to describe that difference is just a way to avoid having a serious conversation about the advantages of Wizards by preemptively declaring them "broken".

I'm not sure there's much point in trying to convince Cosi that the tiers, as commonly understood, are useful. They've made their opinion on the matter quite clear and page upon page of tier related threads have been devoted to debates trying to change their mind.

And, of course, there's a great deal of point in trying to convince you they aren't. The Tiers are, factually, bad. The thing they measure isn't useful, they don't accurately measure it by their own standards, they're not consistent with the term "Tier" as it is used in almost any other context, and they're not testable or falsifiable. People on this forum like them because they endorse the forum groupthink that Wizards are inherently broken and people who like Wizards are powergamers.
