Priest / Warlock Best Method?

[hapiguy314]

Thank you.

so

/assist [Name] (Where [Name] is the main character)
/cast Fireball

is valid?

Yup - That should work. However, you might want to put /follow as your first line - there are some mobs who stun you or knock you down that breaks Autofollow.

/follow Name
/assist Name
/cast Fireball
