Which isn't to say I don't go Heavy/Poise.
I do, but that's a little more complicated, because you have to know when to go Paired, Dual Wield (One of each) and when to 2H for maximum Scaling. Since we're talking PvE here, you don't want the best Damage all the time, because sometimes you're fighting 2 dogs with a Greataxe/Halberd Hollow pair, and others you're getting rushed by trash mobs at the bottom of the elevater from the Shortcut. You know the one? Yeah, 4 of them climb over the wall at once, after you kill the first one, to stunlock you with wild swings, but they're all 1 hitter quitters, and I kinda want to save Health/Estus to go beat up Vordt.
Can't have the Whip/Estoc combo for that (The whip can hit all 4 of them, before they even get close, and the Estoc finish them off with a Power Attack) So, the starter kit for that build is a Raw Straight Sword (Go ahead, and Farm those Lothric Knights) and Parrying Rapier, until you get farther along in the PvE. The Stagger Combo for that is Attack, Left Attack, Power Attack. If you're going Heavy, it's Broadsword, and Spear, or Halberd, depending on your starting Class (Spear for Strength/Warrior, Halberd for Quality/Knight.)
Basically all I do is Dual Wield, and/or 2H. Not really a fan of Block/Shields. Don't forget that the Caestus can Pimp Slap as well as Parry. Oh yeah (Forgot) what a lot of the Mugenmonkey builds that aren't playtested, like the Quality Dual Wielder don't take into account is where does it come from? There's 1 Quality gem early in the game. While you're on Fextralife, go ahead, and look up where you can farm Quality Gems before killing the Cancer of the Boreal Valley. You can farm Sharp Gems in Carthus. (Also, you get 1 Heavy gem in the Undead Settlement, another from Hawkwood the Deserter. If you're going Heavy/Poise, try to limit it to 2 Weapons, but the Demon Fists can't be infused, and already scale best off Pure Strength.)
This is a PvE build:
(Knight, or Merc) Raw Rapier, and starting weapon. (Rapier can Parry in the off hand, get used to the Timing.) Farm the Lothric Knights for your Straight Sword, then advance to the Settlement, add the Whip. Pick up the SSTBs (If you don't already have them) and the Twin Daggers on the way to Farron Keep, and start collecting Shards. Buy a Light Crossbow/Heavy Bolts from Greyrat when he gets back from his first run, beat up the Treenuts to get the Pontiff's Left Eye.
The Twindaggers are for the Swamp, Quickstep. You need the Farron Coal, and preferably Dreamchaser's Ashes so you can buy titanite Shards to get everything up to +3. For extra credit, you go on and Watchdog it for the Old Wolf Curved Sword, and then farm Carthus for the Sharp Gems to Infuse your Arsenal. (Also, pick and chose your favorite weapons to Infuse first. After the LKSS, I +4 that first too from the Large Shards over by Lightning Spear.) Also, for Bosses, Quickstep, and the Pontiff's Left are the best way to deal with the Blood of the Wolf, and Ironically the Pontiff (With his own Eyes!) The OWCS just double each bonus for those 2 rings. I suggest Life, and Chloranthy to get the prisoner's Chain, and Ring of Favor, unless you use Cheat Engine, and/or Pasword Summons to get everything you need from the start. In which case, you might as well go ahead and get Quality Gems/Weapons.
I save my first 2 Pale Tongues for respecs when i get to Rosaria. Yes, i know about all the glitches. I don't tell you how to glitch your way through the game, nobody ever Gets Good by being carried through, and cheesing the game. If you want that, don't go Dual Wield, go full Havel's like all those Overlevel Phantoms running around the highwal with the Spin-to-Win blades. (Splitleaf, Farron baitsword, and RKPUGS)
