When I need to CC on my team for pve, i use focus.

For example, on my DK/Ret team, I use F7-F10 to set focus targets. (My shammys use F6-F10)

So when I press F7, my DK does:
/script SetRaidTarget(target, 1)

And one of the paladins is bound to F7 to do an assist and /focus

This makes it quick to simply target a mob, hit F7, target next mob, F8, etc.

Then after I mark each of the targets, I have another macro that does /cast [@focus] Repentance, so when I start the pull all the targets are CC'd. You can do the same thing with Hex, polymorph, etc.
