This is done by making all of your alts heal spells be "/cast [target=focustarget] Greater Heal", and setting your focus to your main before running around.
How do you mean?
[target=Fatality] Greater Heal

or? Change focus target in my keybindings? :P

I never understood Target Focus - Focus Target anyways. Please explain ^^

Edit: And what i meant with Experience was in this pic:



Number twelve :P He says it in normal chat.
