Specifically, the 1st version of the UA playtest version of the full class, released start of this year: https://media.wizards.com/2019/dnd/downloads/UA-Artificer-2019.pdf
One of my new players has requested to play one and I've skimmed through it and it seems very powerful. But is it really? Does anyone have experience with having one in the party, and what is it like?
Ideally I'd like some hands on experience from someone who often plays days with a limited number of encounters (1-3, usually with 1 really big one).
I'm concerned mostly about the high utility that can be gained from getting a bunch of free magic items (my game does not feature a lot of them) and the Arcane Turret ability of the Artillerist (especially the Defender, but they all seem very strong for costing only a 1st level spell slot)
Of course, those things make up the main powers of the Artificer, so maybe it's not so bad if that's all they get, but I'd rather know before allowing it and having to disappoint the player after he's played a few sessions with it.
