Yes. This specifically is one of the main features that helped me get from 1800 to 2k in season 8.
Wind shear has half the CD of any other classes interrupt spell, so not using it as often as possible is silly.
Macro in like this:
#showtooltip spell
/cast Wind Shear
/cast spell
Where spell is the spell you want to cast. Have each toon use a different spell for this macro, and replace said spell on your bars with this macro. The spells I replace are:
Main: Shocks
Slave1: Lightning Bolt
Slave2: Chainlightning
Slave3: Lava Burst
As long as you are on a target, they will not get a spell off unless they are phenominal at juking, and have ridiculous haste.
You can instead have the above configuration set-up to cast on your focus target, if you are good at utilizing focus targets. This would enable you to be hitting your target hard, while casting interrupts on another target, dps or healer. This is beneficial since the target you are damaging will be smart to get the hell out of range or LoS in order to survive, thus his casting will be interrupted anyway.
Now even with this, you will still not utilize all your toons wind shears 100% (Cast times being 2.0+1.5+1.5+[1.0 or 1.5] = 6 to 6.5 sec, where the CD is only 5 sec) So that means you can also add in a (round robin) key on your bars for:
/stopcasting
/cast Wind Shear
/cast Hex
Hex is optional, but you will still want the first two lines so that no matter what your toons are doing they can stop casting and interrupt an enemy. If the opponents spell is important enough, keep using this macro until the toon with wind shear available uses it.
Hope this helps.
