Right so, I recently found out about the Focus target modifier and about the "2 Keys" saying like overlap, but only for that mechanic and nothing else like for example;
Shift + E for the Modifier Focus Target + An Interrupt like make sure both have the same hot key since the interrupts don't respect the GCD then the other slot for the other interrupt same process but, holding down the button with channels etc, not sure how good this idea is.
This Rule here only applies to interrupts in conjunction with Focus Target Modifier helping out PvE and PvP players alike and it's not a Macro thus not breaking the Code of Conduct!
EDIT: Changed the Concept found out about what the focus target modifier does!
EDIT: I'm not sure how to change the title, ignore that unless I have to make another thread!
