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.
I believe jaronk tier 1 and 2 were defined by the ability to break the game(in all the ways for tier 1 and in some ways for tier 2).
Ability is not obligation.
