Code: Select all
/cast [target=mouseover, exists, harm] Sunder Armor; Sunder Armor;
This is handy for keeping aggro on multiple mobs. Just attack one and click the macro to Sunder it, then put your mouse over the next one (while auto-attack is continuing on the first mob) and click the macro again... move on to a 3rd... and so on.
Give it a try.
