Meh, I'm still working on it. I hate the new lootgen because it's so complicated putting together a final gear set. First, you determine what named items offer unique effects that lootgen doesn't (e.g. melee power on Sightless). Then, you list everything that's available that might be useful on your build, including prefixes/suffixes/bonus effects, in each empty gear slot. With that compiled, you can see what effects are only available in one or two slots and start eliminating extra prefix/suffix/bonus effect options based on that. You'll still end up with some slots that can have multiple permutations, but you should have a good idea of what effects you want where. Then you see if any slots are expendable to be used for legendary greensteel. Fortunately this part is relatively easy since legendary greensteel is so useless on melees. Due to the random nature of lootgen, you'll probably never actually find that perfect set at the highest values, but you'll likely be able to get close to it with less than max values and some missing effects.
I have five builds to do this for. It's tedious and time consuming and I'm at a point in my dissertation that doesn't provide me with a lot of free time. When I do actually have free time, I haven't wanted to spend it pouring over gear lists. I've started this process for this build, but haven't finished it yet. Hopefully new named loot will come out that invalidates lootgen before I get around to compiling a gear set.
