Target self help?

[tripleboxed]

Okay i gotten my team setup corrrectly this time my only questions are when in game i run five resto druids so i need to target myself sometimes instead of auto assisting main. for an example my slaves have "bob targeted" and i need heal on my self but when i cast it only heals "bob" because hes the target that my main is targeting ? point is i need to know how my guys can target theirself and be able to heal anothers?

also when i cast tranquilly they cast and stop and just my main keeps casting weird
