The relative boost in power for the H2H weapons is, believe it or not, drastically higher than almost any other weapon across the board.
Gsword: 73%~ increase from 99 Rag to Senbaak +1 || 46%~ increase from 99 Rag to Bereaver
Great Axe: ~67% increase from 99 Ukon to Razorfury +1 || 48%~ increase from 99 Ukon to Bloodbath Axe
Great Katana: 84%~ increase from 99 Amano or Masa to Tsurumaru || ~46% increase from 99 Amano or Masa to Uguisumaru
Hand to hand: 180%~ increase from 99 Spharai to Oatixur, ~248% increase from 99 Verethragna to Oatixur || 94%~ increase from 99 Spharai to Rigors, 140%~ increase from 99 Verethragna to Rigors
math not exact, I'm sick and it's way too early for this ***, but still it should get the point across.
Ignore all of that, I didn't account for base dmg from skill.
91%~ Vere -> Oatixur, 111%~ Spharai -> oatixur, 47%~ Vere -> Rigor, 63%~ Spharai -> Rigor
The fact that hand to hand is catching up with DRK/SAM/WAR is hardly surprising considering this, and I think it's intentional; they're trying to push MNK up the totem pole, ahead of other 1h jobs, since it's much less "adaptable" and doesn't have as much utility as most of them. It's also served to push PUP up passed other 1h DDs as well, probably an unintended side effect but considering Alternator who knows. Annoying that I actually couldn't beat the urge to buy H2H before sword with my delve points after all the fighting I did to prove how close MNk was to BLU, but things have now changed almost entirely... and I guess it's better than forfeiting myself to DRK or WAR.
