Well, I started a new game on MP7. So far, I'm finding that all my fights are very, very, VERY long. Elites aren't plentiful at the beginning of Act 1, but I've found a few. My MP5–MP6 build looked like this:
Faith in the Light
One with Everything
Seize the Initiative
Beacon of Ytar
I've toyed around with a few ideas and a few skills for MP7. I started with Exploding Palm for Ascension, but EP works a lot better on white mobs than it does on elites. Unfortunately, white mobs aren't a problem until Act 3. I then used Blazing Wrath in place of Ascension, and that's been okay, but I thought I could do better. I toyed around with the idea of using Keen Eye, Overawe, and Combination Strike (and taking out Hard Target and Seize the Initiative, plus Ascension or FitL), but the idea of jamming that third strike in there every four seconds didn't appeal to me; for similar reasons, I didn't try Blazing Fists with Combination Strike.
Although Blazing Wrath was okay, I tried using Foresight and Combination Strike instead. With Beacon selected, FitL takes 15 seconds to cool down, so I used two cycles of FitL as my cue to refresh Foresight's bonus. Overall, this boosts my real DPS by nearly 32% in exchange and maintains my sustain in exchange for losing those four seconds of absolute bliss. Results have been fairly good, although I've needed to live with some corner-cutting. As an example, I encountered an elite pack of Fast Molten Mortar Desecrator cave bats (whatever they're called). In trying to set up my Foresight/C-Strike bonus and FitL and Cyclone. Which promptly got me killed. And killed again. And killed again.
Finally, I said, "Okay, the hell with this—I'm just going to go in there, start pounding, get SOMETHING up for Cyclone, and actually fight." Once I did that, I took them from nearly full health to death, although I had to kite like crazy in a small area. With that fight cleared, I wandered around the caves until I encountered a pack of blue cave bats with Jailer, Molten, Teleporter, and another affix—essentially, a very close copy of the first fight, except that I had all my buffs up. Although I nearly got killed (twice), I managed to win the fight while staying in the same room as the champs. I also conquered a Desecrator/Molten elite pack of scavengers. So, overall, it hasn't been too bad yet, although I could do with a freaking weapon upgrade.
I think I'll stick with this build for a bit and see how it works. I may bring the Echoing Fury out for a bit, too, but I'm finding that I need the LpH more on normal mobs, and the EF replaces my AzT when I'm dual-wielding.
PS. Tried a shield, too. Totally didn't work.
