Thanks for changes in Midnight

Thank you soooo much for the changes to class and UI. These are exactly the changes I was looking for. Getting rid of Unleash Life and combining Healing Surge and Healing Wave etc are really good changes (just to pick a few).

The one question left a little unanswered is regarding the role of mana. Why does it matter for some specs and not others? If the damage is going to come in more slowly then is skill expression going to come from managing your mana?
