Knockdown Feat Grants Spell Effect Immunity

[Peppermint]

Steps to Reproduce:

1. Have an opponent use the Knockdown feat to render you prone.

Expected Result:

- Gain immunity to the Knockdown feat for 18 seconds.

Actual Result:

- Gain immunity to the Knockdown effect for 18 seconds, granting immunity to Wing Buffets and the knockdown component of spells such as Grease, Gust of Wind, Great Thunderclap, Hellball, etc.

Notes:

The existence of this bug allows for exploitative and/or non-intuitive gameplay behaviors. For example, casting a Hellball after your ally has been knocked down in group PvP (whether by friend or foe), allowing him to leverage his newly acquired knockdown immunity to wail on an enemy with impunity for Hellball's duration.

Suggested Fix:

1. Adjust this behavior to grant immunity to just the Knockdown feat.

-or-

2. Add a cooldown to the Knockdown feat instead.
