I need advice on how to handle the behavior of a fellow PC.
Our group formed about 4 Months ago, we are 4PCs + 1DM. We are playing D&D 5e Icewind Dale: Rime of the Frostmaiden. Our DM puts a lot of effort into the campaign. I really like it (it's my first time playing). We are now 7 sessions in and at LVL 3.
But there is one player with whom it didn't quite click right from the start, and now his play style kind of annoys me. He plays a Wildfire Druid. He claimed he has some experience with D&D, but he constantly forgets how his class feature works, like we look it up every session when he uses it. At the moment he is cursed and can't long rest, so I'm honestly happy he's limited to cantrips (fights went on a lot faster) but even there he couldn't remember how much damage his one attack cantrip does and he nearly killed himself by walking into melee with the Big Bad Evil, despite having Firebolt which has got 120ft range. So maybe he is a slow learner and druid might not be the best class, with all their options, and I could maybe live with that.
But recently he also started to metagame quite more and role-plays way less. Our role-play is rather light (I myself got still a lot of room for improvement) but most of the time our characters speak to each other in character, which he mostly doesn't.
I already told my DM, that I disliked his recent play style. But we are the first group he DMs and I don't know if he can handle this situation.
For now I will wait how our next session plays out, but should (if nothing changes) I confront him directly, or ask the other 2 PCs first, if it's just my problem or if they feel the same?
