Just spent 30minutes on the 'be all end all' encounter of mid content, Matron, to receive the below hat. Does it have more green stats? Yes! Does it have more potency and crit? Yes! Unfortunately, because it was itemized for 22 Ability mod, and nothing else, this hat is worthless. Even if it only had casting speed or reuse, it still wouldn't be worth wearing because the hat from Labs (The easiest raid zone) has 4 blue stats, including both casting speed reuse. 22 Ability mod is no where even close to as equal as the equivalent casting speed or reuse. 'End game' loot needs to have both casting speed and reuse, or even 5 stats (Cast + Reuse + Abmod) in order for it to actually be an upgrade, regardless if you give it a higher 'ilvl' with more potency / crit.
