5.24 classes I've played:
Sorcerer: definitely deserves S tier. So far have played to fifth level and innate sorcery is just a MASSIVE buff. Innate sorcery + chromatic orb, even at low levels started getting me the stink eye from the DM.
Paladin: also deserves S tier. convinced the DM (different from above) to let me try an oath of the Noble Genies Paladin. And it's REALLY really good. AC is good (5th level AC is 18 but 21 when it counts with Parry from defensive duelist) and damage output is very good, especially when it counts.
Have DMd for:
Fighter: agree on A tier. The buffs have really improved it. And it's kind of hilarious to watch the fighter now getting some of the best out of combat rolls too.
Barbarian: one trick pony, but it's a GOOD trick. The Berserker barbarian is a true beast now, and no more worry about exhaustion! Not as well rounded as most of the other classes but I'd go B- or C+. Not too much disagreement. I'd love to see a world Tree Barbarian in action, I think it would be fun and different
Warlock: the warlock in my group is certainly effective,but doesn't stand out. B is about right.
Wizard: maybe not buffed like the other classes, but still has a massive and diverse amount of levers they can pull when necessary. Certainly not C! I would still go A tier, especially when played effectively.
No new insight on the other classes yet.
