In the playthrough I just finished I had my Paladin mostly running a great sword but took the defensive fighting style and ASIs at 4 and 8. This time around, I was considering leaning into the great sword and/or 2-handing some of the powerful versatile weapons one tends to run across in the main campaign (staying vague here to avoid spoilers). To do that, I think that means taking great weapon fighting as the style, and follow-up attack at 4 and an ASI at 8 for maxxxxx deeepsss. I could also see not bothering with great weapon style and keeping defensive, just to keep the survivability up. But all of that is pointless (IMO) if I‘m constrained by the availability of a good 2-hander (versatile Magic weapons seem way easier to come by overall).
Typos happen. More so on the phone.
