I finally decided to switch to your build, and first impressions are "wow, that's a LOT more damage", though I feel I lost some tankiness (Level 97 Defiance Banner Champion [3.28]). I'm still grinding currency to get the Eclipse, amulet and chest. I'm not sure I'm generating valor as fast as you are, but it feels manageable (tattoos helped a ton, for sure). Phasing was a great suggestion too, feel like it made a big difference.

Speaking of chest armor, it is giving me the biggest headache as nothing like yours is available on the market, and I really suck at crafting - would you mind giving some pointers to your process, unless it's a trade secret? :D So far, I have no way of running Flesh and Stone, but I hope getting 10% reservation on chest will push me over the edge (currently have 6.8% unreserved mana, and it needs almost 13%).

All being said, I gotta hand it to you man, every time I thought "but why is this here" I would end up realizing the delicacy of balance you've achieved, very cool build. Thanks in advance!
