I have the vindicators neck, but am considering to try the sso pendant out (the aldor version).
According to maxdps, however, the vindicators neck is superior. But I dont trust maxdps that much tbh.
From calculations made on wowhead the aldor proc equals a static 40ap, making the total ap of the neck 104, which is much higher than the vindicator's one (even with a 20 ap gem in it). However u lose crit on the sso one.
How to u see those two necks comepared to eachother?
