Sorcerers with spell resistance

[Esiminar]

I’ve been thinking for a while that it is silly for a high level spellcaster battle to rest on initiative. So to combat this I have been playing around with the idea of giving sorcerers and wizards spell resistance.

I have come up with this so far:

Wizard/Sorcerer level + 5

or

Wizard/Sorcerer level + 10

The first would mean that a sorcerer or wizard would only be affected by casters of the same level three quarters of the time, and the second of them would reduce that to half the time.

What are your opinions on this?

P.S. I have not included any other spellcasting classes as I work the differently.

I suggest giving them all Reactive Counterspell instead. That means that most spells in a spellcaster battle will be countered.

I have my own Archmage-style prestige classes, where spell resistance (at caster level +5) is one of the powers available

Since Greater Spell Focus is a prerequisite here, it basically only means they don't fear lesser spellcasters.
