That being said, look at EDs that don't directly empower your character for features that will shore up weaknesses.
LD on a caster for example: the Str/Con enhancements and even the action boosts can allow you a chance to Melee against creatures that are highly resistant to your damage spells
FoTW has wisdom enhancements and Boulder Toss
Shadowdancer has some nice defensive abilities
Now some of these EDs don't offer anything at the lower levels and some do. But sometimes it takes looking for positives instead of looking at the negatives to allow you to "stomach" through to access what you are actually after.
