So very curious if this game allows the feature to cast on your targets target.

Example. Your playing a healer and have a tank targeted but would like to cast a DPS spell. Some games allow you to simply target the tank and cast and you would hit the tanks target.

Or you can play a DPS and have the MOB targeted but see a group member could use some quick healing. So again you cast the heal, healing the MOB's target.

This sort of thing can make life very much easier.
