9/9 PD doesn't reach the same caps as berzerk. It's attack rate less. And even if it managed it even with a cupid energy source it couldn't sustain it long enough to match berzerk.
Basically, a 9/9 PD can't reach the 200ms. Even with a 9/9 Cupid, it'd still need more energy to sustain the 5th stack to achieve thr speed cap long enough for it to be viable enougu to compare it to a bezerk. Difference being, a Zerk duke will constantly swing at a faster attack rate compared to a non would, thus allowing it to constantly stay at 200ms. A non bezerk pd even once stacked, will drop out after about a second so even though achieving the speed cap, it wouldn't be long enough to see a benefit and match zerk because the extra 30% on a 8/9 duke allows it to sustain it constantly.
this has get to the point where it now boring. All those maths. It all good information and proof. However what we really want is to do the uncap. And what happen to the past thread about bring back the uncap atk rate.
