Its value does not change with the number of attacks made.At 40% base accuracy, OGWM does 75% of not using GWM (ie: worse). It breaks even between 50% and 55% base accuracy.  At 70% base accuracy it's doing 25% more damage than not using it. At 90% base accuracy it's doing 40% more damage than without it.New GWM scales inversely with the number of attacks. It does not vary with accuracy. It can only proc once per round, so the more attacks you make, the less it contributes in damage per round.With 1 attack per round, it adds 48% to total damage. With 2 attacks per round it adds 24% to total damage. With 3 attacks per round it adds 16% to total damage. With 4 attacks per round it adds 12% to total damage. With 6 attacks per round (level 18+ fighter, Cleave weapon, and GWM crit proc, though I'm cheating and not calculating the different damage from the last two hits) it adds 8% to total damage.With 1 attack per round, NGWM will basically always outdo OGWM. With 2 attacks per round, it will tie OGWM at a base accuracy of about 70%. With 3-6 attacks per round, NGWM is roughly on par with a 55%-60% base accuracy OGWM.A level 5-10 fighter not using Polearm Master will generally be on par between OGWM and NGWM, at about +25% either way, assuming an accuracy around 70%.  With Polearm Master, or after level 11, when reaching 3 attacks per round, NGWM is generally worse than OGWM, unless accuracy is kinda low (60% or less).For a barbarian, if GWM is picked up at level 4, NGWM will generally be better. At level 5 with extra attack, OGWM will almost always be better due to the accuracy boost of Reckless Attack. Moreso after gaining Polearm Master, or using old Frenzy for a third attack.That said, the extra +1 Str that NGWM provides shift things considerably. For example, going from a 17 to an 18 Str boosts both base damage and accuracy. This also means there's slight inverse scaling with accuracy, though pretty minor; not nearly as dramatic as OGWM.So if you go from 17 to 18 Str, NGWM is now worth about 60% more when using 1 attack, 40% more when using 2 attacks, and around 25%-30% more for 3-6 attacks. That means that even with a high number of attacks, it's comparable to OGWM at around 60%-65% base accuracy.Broadly speaking, I'd consider the two versions comparable. As you get higher accuracy and more attacks, things lean more towards OGWM, while lower accuracy, fewer attacks, and Str mod bumps favor the NGWM.  It's hard to say exactly where the transition point is since there's so many things that can vary by character build or encounter.</blockquote>
