Opens the MRT "Personal buff icons during ready check" window when a pull timer (/countdown, bigwigs pull, dbm pull, or rt pull) is made.
By default the window will close when entering combat, you can disable this in the custom options.
If you want to manually toggle open the window you can do so with the following macro:
/run WeakAuras.ScanEvents("WA_SHOW_MRT_BUFF_WINDOW")
Must have Method / Exorsus Raid Tools installed.
