more attack speed barely affect Rolling slam

No idea if intended or not but just in case:

as title say, the martial tempo support doesnt give rolling slam 25% more attack speed, on my character, it goes from a 0.49 tooltip attack per sec to 0.51 (4% more).
Tooltip time seems to be accurate to what is observed in game.

Increased and reduced attack speed also seem to affect it way less than it should. Might be a bug due to the skill having multiple stages.

I believe it is working as intended. The formula for the skill's atk speed may appear odd due to the +1.5 seconds to total atk time. When using the skill with a 1 handed mace + the movement speed shrine, the atk is indeed a lot faster, just like using Stampede under the same circumstances.

The atkspeed affects the startup time of the skill, while movement speed affects the "multiple stages" of the skill.
