hmmmmm juicy XD
It's very intresting that you ask for a calculation when so far, every kind of math i've shown you resulted into a tiny Hiroshima in that walnut brain of yours. Anyway, like they say, 3th time's the charm xD
Assuming following gear: (you said you're a proper geared templar so this should certainly be reachable for you)
- Upgraded club (50% AS)
- Silva pet (30%)
- Opaniel Guarder (15%)
(not counting party buffs or stones on weapon)
One handed mace: base D: 900
Before nerf: 30% AS Blunt --> 900/(1+0,5+0,3+0,15+0,3) = 900/(2,25) = 400,00
After nerf: 12% AS Blunt --> 900/(1+0,5+0,3+0,15+0,12) = 900/(2,07) = 434,78
With this setup the attackspeed delay difference between the old and new blunt mastery is 35MS (or 25MS if you use the 38% AS stone from Yinggamers example). This delay becomes less and less when the amount of attackspeed multipliers increases (e.g. rumir growth, having 38% AS stone on ur trans wep, priest ulti and so on). This is (like petebebz explained so well) due to the asymptotic nature of the way this formula works.
You've now seen: linear, exponential and asymptotes, I just hope you're keeping notes and prevent me from making more quotes so that I don't have to devote any more time to sink that ship you're in that to begin with, was never afloat.
