Accuracy cap for summoner for T9 is supposedly 491. Right now with the Scylla robe I'm at 487. I always thought cap was the minimum of what you wanted? If I switch to the evenstar coat I'll lose accuracy. Granted I'm not currently running SCoB but they are saying that Shiva EX has accuracy caps approximately the same as T9. My FC isn't hardcore into raiding so I'm not as informed as I should be.
