Overall, this update is a huge help for healing and protection monks; it will make our game play a bit more enjoyable. In short, I expect to see the Mo/Ne replace the Mo/Me. Mesmer secondary took a big hit.
For energy management; it is a win. For those that want to continue to use Energy Drain, it'll be about 33% less effective due to the increased recharge. However, for those that don't want to spend time finding an Elementalist to drain -- it is a win, far less energy will be leaving our bar with the new ED. So, I look at it this way -- we get our Elite slot back. To add icing to the cake, Divine Spirit, once a favorite of mine, looks like it needs to be dusted off -- the extra 4s will mean 2 more spells, and those two additional heals will make it far easier to justify the 10en cost. I think most healing / protection monks will now be using Offering Of Blood plus Divine Spirit to power their healing engine. I think this is a good sized win.
For hexes, we effectively lost Hex Breaker. However, the primary goal of that skill was to cause the caster pain (hence the damage); this skill should never have been usable at 0 domination. What we get for its replacement is Holy Veil, which is now far more effective! Since you can cancel Holy Veil at any time, expect it to be the hex removal of choice; it might even replace Divine Boon + Contemplation of Purity for pure-healers. Unfortunately, you won't see this monk abusing it since I don't have a mouse (and you cannot cancel maintained enchantments w/o a mouse). Overall, I think this is a win -- but not a huge win.
For enchantments, it is a bit worse. Rend Enchantments is no longer a "necro self-killer", and Desecrate Enchantments is cheaper. However, their recharge still prevents them from decimating an enchant-heavy monk.
For actual casting, it is a huge fantastic win. Diversion is effectively worthless -- its extra cast time and recharge make it very hard to work with someone equipped /w Holy Veil or Boon+Contemplation. Furtermore, the nasty continuous-interrupting Ranger build is now (thankfully) nerfed. Together with Energy Drain nerf; I think we might actually get off some spells, rather than being degrated into a "run-and-hide" class.
Of the fun changes for mo/ne, I think Blood Renewal is now crying for some attention. It has received two buffs in a row, first on the healing power and now on the reduced sacrifice. I will definitely be trying a Blood Renewal + Infuse Health build in the near future.
I'm also happy about the Pacifism change; a 3s cast made it completely unusable; at 2s I might try it again. For us divine-favor junkie (and who isn't?), the buffs to Divine Healing and Divine Intervention are seriously welcome.
As you know, I think that the monk should never be able to do as much damage as an elementalist (else the elementalist should have better healing, no?), and therefore, I'm absolutely tickled /w the nerfs to the smiting line. In my opinion, they were way over powered; and perhaps this might help address that problem. The indirect effect of this will be clear to PvE players -- more monks will be willing to form pick up groups with you since their ability to solo got a serious hit. This is a good thing for team play.
Oh, one other note relating to PvE monks. For once we now have a serious skill to help reduce our healing burden -- the Doldak Signet on our "tank". When we're asking for a tank, we should be asking them to bring this wonderful skill; with knock-down protection and +40 amour, our tanks will need less healing. And the plus side? For 5-10s after combat they will be too slow to charge into the next group! Hurray!
) and be the love of your team. Max energy pips constantly.....3.3 energy regen per second....
