So I'm a long-time player of DnD 5e who started off with Pathfinder 1e, and who is now giving PF2e a shot. My group and I are all newbies to the system, but we love how open-ended it seems as far as character creation is concerned. We're more than a little lost as far as party composition goes.
I've done some research and it seems like party optimization is more important than character optimization, as in it's more important to choose actions and classes that mesh rather than building up numbers like in 5e. That's the point where we seem to be drawing a bit of a blank. Like I said, we come from 5e where being a little selfish with your build and actions is pretty standard, but it seems like that might not be the best way to go in this edition.
My group seems to be pretty interested in running with a Swashbuckler, a Summoner, and a Gunslinger. I think the Summoner might be a little iffy just because of how intricate the class is, but the Gunslinger is 100% set. I was leaning toward Thaumaturge because I love the base class, but I'm not fully invested at this point just yet. I also like the idea of some sort of gish-like class that relies on buffing myself and my allies, but I haven't seen anything like that in this edition.
It seems like having a caster and some method of buffing/debuffing is really important in this game, and we don't have anyone for that role at this point. What do you guys think about that party comp? Is there something I should look into playing that might provide a bit of a buffer/debuffer?
