Latest patch notes for 1.9Follow

http://powerwiki.na.aiononline.com/aion/Korean+PTS:+March+3rd+Test+Server+Update+1.9+Announcement

Too long to copy/paste, absurdly large number of changes, mostly to itemization and drop rates. A few class changes as well as a new stat that appears to allow spells to crit (that thing everybody thought magical crit did). Also summoned spirits scaling with bonus gear stats from an SM.

Good stuff in there, give it a read
