Buff Canceler

Unlike many other Buff Canceler WAs or Addons this minimizes the amount of macros that are used, use the command below to see

/script WeakAuras.ScanEvents("PRINT_AURO_BUFF_CANCEL")

You can add or remove buffs you want to cancel in Actions Init

To use this put /click ABCButton1 in your macros

I recommend putting another macro on your bars with /click ABCButton1 and in your main abilities clicking that button instead.
This allows you to turn off the buff canceler by just dragging that button off your bars, you can identify it using FStack

As an example my Bloodthirst Macro looks like this

#showtooltip
/stopmacro [channeling] 
/startattack
/cast Bloodthirst
/click ElvUI_Bar6Button11
/use Elixir of Poison Resistance

ElvUI_Bar6Button11 is my macro that clicks ABCButton1, which looks like

/click ABCButton1
