I wanted to make a mid tier quality build for PvP, Co-op and playthroughs. I went 27 STR and 30 DEX for best damage out of my favorite quality weapons, Longsword, Claymore, Zwei, Composite Bow. While still doing pretty good damage with some other favorites like Estoc and Rapier. Although I don't have 40 Dex, the +15 Falchion buffed still has the highest DPS against 4 Kings, Longsword has 20 more AR, but its just a bit slower to not keep up in DPS. I only use the Falchion for Four Kings usually, every other fight is with Claymore, Longsword, Zwei or the occasional Gold Tracer to bleed some Demon bellies.
I did a standard SL 1 Run a long time ago, it was challenging, but boring, I prefer to have more weapon and build variety. I much prefer doing Starter class challenges, or low level challenges with 16 STR and 14 Dex for weapon variety, but minimum Vit and End and no Elemental upgrade paths. Still very challenging, and much more fun. Cycling through a Reinforced Club, Blacksmith Hammer, and R1 spam with a buffed Dagger got old really fast, it's just not how I want to enjoy the awesome combat in Souls games. I can manufacture challenge easily and in a way I will enjoy, and I have a viable PvP and Co op build on top of it.
