wow quest:triage (first aid)  

Do:

• hotkey the triage bandages. If you have a heal ability you use a lot, put it there for the time being.
• zoom to third person so you can see all victims.
• preselect the next dying victim before the bandaging is done on the current
• look for a pattern: undead are always critical, trolls always badly injured, and orcs always injured.
• stand between the two rows about level with the middle of the first two guys. They'll all be within triage range from here.

Do not:

• let a dying patient throw you off. Expect to lose 2-3.
• use ctrl+v to see health. They all have full health till the moment they die. It just clutters up your screen so you're better off looking for that pattern.
