Why is my Leap Slam slower with a faster weapon? (details inside)

I got this item yesterday:


And I have been Leap Slamming with BrightBeak until now:



Now, my passive tree is as follows:


As you can see, I have %10 more attack speed with swords thanks to Blade Master and the prior small node.


I was expecting an increase in my attack speed with my leap slam but instead, it is slower in both tooltip and the actual animation. I asked a bunch of people but they all said it doesn't make any sense, so I decided to ask you people hoping someone can provide a logical explanation.

Here are some screenshots:



You can clearly see my attack per second increases with the sword, yet leap slam is slower for some reason.
If anyone has any idea, please tell me.

Thanks

It's not a big mystery.

Leap slam, sweep, whirling blades and such have their own base attack speed, it doesn't depend on weapon used. But if you got increased attack speed on a weapon, passive tree or gem it will speed up those skills too.

So, a 2H axe with base attack speed of 1.0 and +20% attack speed will do leap slam faster than a rapier with base attack speed of 1.7 and no increases to attack speed, even though rapier will attack a lot faster with other skills.

Understood. Thanks for the info.

Now I know :)

for the fun of it you can link leap slam with multistrike. impressive attack speed increase, you will look like a squirrel on extasy.

Anyone know if movement speed pasives speed up leap slam?
