The new SoO trinket currently increases cooldown recovery rate of abilities by 39% (plus proc is +11000ish to main stat I remember)
the abilities can be found in http://ptr.wowdb.com/search?search=R...gorized-spells
For some classes it looks very mandatory (for example rogues get smoke bomb, cloak, shadow blades, vanish, cooldown and stuff)
If it comes live some classes can forget the 10% dmg reduction I guess
