I am in a pinch with the new DD SIN ASPD Formula

[Transcend]

DD sin's are rare,hard to play also,but gravity just reduced their ASPD again (not sure)
Please help me decide,my server is to be open to the public sunday

DD SIN ASPD FORMULA
For Assassin with Dual Wielding:

Previous Fórmula: (From Doddler)

wASPD = (200 - (JobASPD[n_A_JOB][n_A_WeaponType] + JobASPD[n_A_JOB][n_A_Weapon2Type]) /2) *1,4

New Fórmula that i propose:

ASpd Base (For Dual) = 280-(1351/135000)*[(200-ASpd Base Weapon 1)*(ASpd Base Weapon 1)+(200-ASpd Base Weapon 2)*(ASpd Base Weapon 2)]

ASpd Base = (200-Weapon Delay)

ASpd Formula: 200-(1-Speed Mod)*[250-AGI-(DEX/4)]*(200-ASpd Base)/250



This means they should have less ASPD by lvl 99 a 99 AGI sin will have less then the older Formula.
Is this change correct ? because i don t see the point of reducing their ASPD now.
