I usually play ranged martials. In 5e, is was basically exclusively rangers, and in AD&D2 it was a ranged fighter. I’ve always kind of played fairly timidly, trying to stay back, kite enemies, and avoid actually taking hits.
I’ve only gotten to play PF2 as a GM. My table only has 2 players, so I have a GMPC tagging along with the party. I wanted someone explicitly defensive in nature, so I originally spec’d them as a Champion. It wasn’t the best fit for who the character was supposed to be – they weren’t devote, and they weren’t in any way magical – but I made it work. When the Guardian playtest launched, I respeced him immediately.
Guardian has been a real breath of fresh air for me. Since the GMPC is there to be a meat shield, and because I’m not especially attached to him, using the Guardian as a mobile interceptor has been a lot of fun, even as I do everything to make sure he exists solely to shine the other players. Also, GMing has really helped me deal with my hesitation to get into the fray – the NPC monsters exist to be killed, and I’m happy to put them in positions to be killed.
If I ever get to a PF2 table where I’m just a player, I’m absolutely rolling another Guardian. Especially with the buffs that came with it’s official release. A utility defender is scratching an itch I didn’t know I had.
