[Monk][Talent] Rushing Jade Wind and Haste ticks

[mental^depress]

WoW Freakz spell link: https://www.wow-freakz.com/spells.php?spell=116847&&name=rushing-jade-wind
Bug description: I. Rushing Jade Wind should have only 8 ticks until 28.40++ % haste.
Proof:

Currently, with 0% haste at level 90, Rushind Jade Wind ticks 9 times.


Information:

Rushing Jade Wind should have 9 ticks ONLY if the player reaches more than 28.40% ~ haste. - http://www.mmo-champion.com/threads/1331002-PTR-5-4-Rushing-Jade-Wind-Question ( Dracjin post. )
People have also tried to reach the nine tick number, but, without success if you are under 28.40% haste. - http://us.battle.net/forums/en/wow/topic/9972877492


II. Another problem is that the ticks aren't calculated exactly, even in their milliseconds.

Example:

With 15.93% haste ( 6,333 haste ) - The spell says the following: 5.11 seconds cooldown, 5.11 seconds duration, deals damage to all nearby enemies every 0.64 seconds.

Now, if we calculate:

5.11: 8 it will result into: 0.63875

* 5.11 - being our spell duration
* 8 being our ticks number
* 0.64 being our number that explains how often the spell will hit
