I'm not sure if you can use "or" statements. Just make 3 seperate macros.

Also, I suggest making a

/assist WarriorCharacter
/cast Moonfire

or /cast Wrath Macro.

Even though they're out of group, if you wait until the mob is below 80% health and have the druid do some damage, the mob will go down faster and the warrior will get 100% xp.
