Since Dispels were made to check SR, a simple Blur now gives immunity from a Bard-cast Lesser Dispel. I tested this earlier after Staring Death told me about it. This makes one of the more dangerous offensive tricks of bards (dispel spam) fairly useless since if you're firing dispels at someone, Blur is likely to be a factor.
This could be fixed by making Blur give immunity to all spells with an innate Level of 1 or removing Dispels from those affected by SR. They were some of the few spells you could use against Resistant enemies..
