While true about damage spells not being the prime focus of the artificer, the overly conservative buff/debuff/control spells with excessive concentration requirements is also something that hits them in an area they should shine in.The Artificer isn't really a damage Spell kind if Class: that's why they have weapons. The Spells chosen ought to be more support based, with the Martial half supplying the damage with assistance from guaranteed magical weaponry and armor.
5e reduced it to a half caster from 3/4 caster. Here is the old paladin, artificer, & wizard spell progression side by sideWhat do you mean by 2/3 caster or 3/3 caster?
Artificer is still a half-caster, it just gets cantrips and it gets spells at first rather than 2nd like Paladin and Ranger. But it's the same spell progression otherwise.
