Mind Blast - Stealth Nerf

Ok now, I am very upset. Blizz and their stealth nerfs is most frustrating. In fact, I have left several MMO's because of nerfing! Anyone else feel this way.

At 43, my mind blast with +168 shadow was doing 810+ on crits, now I am at a best of 711, With shadow weaving up, I should be over 800 on crits, now I see upper 680's... A 15% drop in damage on my most favorite spell.

The SW:P nerf is bad enough, but mind blast too!!!
