Conditional based on targets name?

Not sure if this will make sense - is it possible to do a conditional based on who you're targetting?

Logic being - "If my target is person X, do this - if my target is person Y, do this" - Those of you who have read the no focus manifesto, you know why.

Just tossing around ideas - I run tank + 4 shammies sometimes, and just the 4 shammies in other occasions. I'm at work, hence failure to test... and I'm bored.

In a word "No."

You can not cast a spell based on the the target. You can use keyclone or HKN "hotstrings" to cast spells based upon the the initiator. However, the logic to cast spells based on the target does not exist in the game, there are a few creative macro's that can cast a heal on helpful targets, and throw damage at harmful one's but that's about the limit of the capability.
