I was speaking (..Well, typing) more with balance in mind. Yeah, I get what you're saying from an RP perspective plenty.
Granted, I'd rather see them stronger than spamming dispels nonstop. That's still going to strip buffs from those cast on (If I remember correctly.. starting with those spells of lesser levels.. Like protection from Allignment)
Also, weapon buffs (at least, the spells) should be able to be stripped. If they're not, I'm not complaining.
Varnishes definitely should not be dispelled via magic, that's my bad there.
Debating balance in the issue isn't really a good idea, though, because.. Well, regardless, you're going to need decent-level casters that could do it on their own with a bit of rest. It might kill the mood/fun of it for some (like me), but it's still.. Possible for some and completely out of this world for others.

...Back on topic- Yeah, anyway, dispel magic + Fear Aura = Bad for everybody.
Then again, I hate fear auras altogether. Seems kind of iffy to have that jerk in the robes be much more willing to look a bone-bat in the eye than a seasoned warrior to me.
