From this and this, I get that there are some (official?) tiers for classes in D&D 3.5e.
Is there such a thing for D&D 5e? If there are, at least I expect them to be separated across class archtypes, not just classes.
For reference, I'm using the tiers from 3.5e. For example, Tiers 1 and 5 are:
Tier 1: Capable of doing absolutely everything, often better than classes that specialize in that thing. Often capable of solving encounters with a single mechanical ability and little thought from the player. Has world changing powers at high levels.
Tier 5: Capable of doing only one thing, and not necessarily all that well, or so unfocused that they have trouble mastering anything, and in many types of encounters the character cannot contribute. In some cases, can do one thing very well, but that one thing is very often not needed. Has trouble shining in any encounter unless the rest of the party is weak in that situation and the encounter matches their strengths.
