Lua Code:
local x = ActionButton1Cooldown.SetLossOfControlCooldown
hooksecurefunc(getmetatable(ActionButton1Cooldown).__index, 'SetLossOfControlCooldown', function(s) x(s,0,0) end)
Still causes a cooldown shine, probably not the ideal solution.
I think replacing the function outright will end up causing taint though.
