I know that maybe ppl know it but i have never tried it before until now (when i was clearing bank before MoP).
Simply the bug is that u donot need to wear fandral's staff to keep buff.
1. Equip Fandral's staff
2. autoatack something
3. change weapon
4. keep combat
Its usefull mainly for raids where u got combat for whole fight and so keep fire cat for whole fight and its good reason to save this staff to MoP and be still "usefull" at leas visually :-)
I know its not big "exploit"
Sry for my bad english donot be grammar nazi![]()
