Update: my all ranged party got to level 4 and had no problem with Minthara and did Guts from her room agrroing everyone outside. Wyll went down but otherwise it was fine. Currently no wipes/loads so far.
Generally the 18 dex Archer Fighter is strong due to very good to hit chance (+2 from Archery) though ranged damage (with +1 longbow) is outdone by a maxed Hex-Warlock (1d8 + 1 + 4 max compared to 1d10 + 1d6 + 4 max) it hits a lot even on flat ground and the Battlmaster tactics can be very effective. I have tried out the various new Battlemaster stuff and the disarm attempt does not show up rolls in the log. I have manged to disarm things but I don't know what it is rolling against...? (Menacing is Wis and Knockdown is Str for reference) Knock prone works fine and the rolls are in the log. All three can be fun but Menacing (which was already there) is the most effective against low Wis foes.
