As the title says. We ran level 1 the other day and I noticed the artificer basically stunk.
No sneak attack, didn't deal much damage no spells except cantrips. Probably level up near the start of next session.
The Sorcerer was also a big pile of meh.
Fighters at least deal decent damage and can heal themselves 1/shirt rest. Probably one of the better level 1 classes tbh.
I guess it depends on what makes a character interesting to you. I've found all classes can be fun at Level 1 really, it just depends on what you want to focus on. Of course depending skill selection, background choice, and were you put your typical ability scores, I have found (for the most part)
Barbarian -- Good combat, decent exploration, poor social (2,1,0)
Bard -- Decent combat, decent exploration, good social (1,1,2)
Cleric -- Decent combat, poor exploration, decent social (1,0,1)
Druid -- Decent combat, good exploration, decent social (1,2,1)
Fighter -- Good combat, decent exploration, poor social (2,1,0)
Monk -- Decent combat, decent exploration, decent social (1,1,1)
Paladin -- Good combat, poor exploration, decent social (2,0,1)
Ranger -- Good combat, good exploration, poor social (2,2,0)
Rogue -- Good combat, good exploration, good social (focus is usually in one and the others are decent) (2,1,1 in some combination)
Sorcerer -- Decent combat, poor exploration, good social (1,0,2)
Warlock -- Decent combat, poor exploration, good social (1,0,2)
Wizard -- Decent combat, decent exploration, decent social (versatile spell choice allows focus) (2,1,1)
So, I have found Clerics tend to be the most one-dimensional at level 1, focusing on one of the three pillars.
For myself, Druids, Rangers, Rogues, and Wizards tend to be the most enjoyable.
But, it will vary according to your desires and exactly how you build your PC. I think it is only really disappointing if you want to be good at one aspect, but failed to build for it.
EDIT: Just to clarify, this is in respect to level 1 only.
Also, at our table level 5 is the rebuilding level. It is the only time you can tweak your character, including scraping it completely and making a whole new level 5 PC for the remainder of the campaign.
