Im new but id like to share some usefull tips for anyone to use.

1st but most important to me is Healers have to die addon

http://wow.curse.com/downloads/wow-addons/details/healers-have-to-die.aspx

It singles out healers by putting a big red cross overtheir heads and when you mouseover 1 it dings same as when you target 1. Very handy if you ask me

Now some macros for a rogue.

1. Sap stealthed targets or nearest target

#show Stealth
/dismount
/cast [stance:0] !Stealth
/targetenemy [harm][nodead]
/cast Sap

You can put in a shadowstep between Sap and targetenemy for distand targets. Spam it and no rogue or cat will escape your Sap

2. Counter a rogue when he opens with Sap-Cheap Shot.

Wait for the Cheap shot then press this macro

#showtooltip Bloodthirsty Gladiator's Medallion of Tenacity
/cast Bloodthirsty Gladiator's Medallion of Tenacity
/cast Vanish
(/cast Shadow Dance) only for the extra Ambushing
/cast Shadowstep
/cast Cheap Shot

Now hes yours to open on :) Remember this is a double press macro, hit it twice

And my favorite but only for undeads is to eat when you kill an enemy with Cannabalize while in stealth

#showtooltip Cannibalize
/cast [nostealth] !Cannibalize;
/cast [nocombat] !Stealth; Vanish

This only works when you macro it cant do it with button pressing

If you have any ideas for new macros please tell me i have full knownledge of the syntax so anything is possible
