Dunno if this post is really worthy of a post but lets point some clear things out from this patch.
1) They want to heavily tune down "mana-regen" tactics, this is a great decision it means you have more room to make mistakes as a healer and this sort of thing.
2) Removing Illumination, I never liked this talent as like a pathetic amount of mana, it worked better with 100% back on crits because it just felt nicer, but it's too hard to balance around this mechanic at all levels of gear I would presume and so it's been removed and probably for the better.
3) ZG IS GONE!!!?!?!?!!!!????!!!! Please make those mounts welfare so I can laugh at a certain somebody who farmed those for over 4 years and only just got both of them recently :)))).
