I use focus for my DPS, and targets for CC...

For example, before pulling I target mob1 and click the "dps1, /target focustarget" button, then target mob2 and mob3 the same way...

Now warlocka, b, and c each are targeting a diffrent mob...

Then on my paladin I target the DPS target...

Click the fear macro for each of my warlocks (fearing what they have targeted), then click my shadowbolt macro.. that macro uses "/cast [target=focustarget] Shadowbolt" to target...

End result:
The clones Target is for CC and uses [target=target] style macros, and my focus target is the DPS target using [target=focustarget] style macros.

Main dies I just click the macro to get the next focus and continue.

Only problem is that wands dont work.

I have thought about reversing the setup so that wands to work, but have not yet changed them.

This setup is from a thread on this site
Using someone elses good ideas
