You don't really need anything other than anticipation to move out of the way.
Also each class has a great way of dealing with these types of baddies. Your kill order should be casters and TD spammer first. For example if I had FoD, I'd finger them. Or if I was a Wis build I'd Implode or Mass Frog them.
If you want to stay in blasts, then pump your reflex and use spell absorbtion.
