Ok, I'll go first. I spent past 14 days mostly on GD and the expansion, and this is the best I could do so far. My first char, and I think it turned out pretty nice even if I had no idea what I was doing most of the time. I still have a lot of items to upgrade, my average item level is only 78. I don't think this character qualifies as big guns, I saw witchblade youtube video with twice as much DPS (but only 14khp and mediocre poison resist). But survivability is pretty nice, despite not using shield. I stacked as much ADCtH as I could find without using Haunted steel (which costs too much DPS). As long as I keep the damage going and with 1 point in force wave to provide some breathing space in large crowds, I can facetank almost anything in the game. Almost. I could survive in melee with mad queen for a few seconds, but her life drain aura makes it a very long and difficult fight. I have yet to dare to provoke wrath of the Ravager. Malmouth boss still managed to kill me once the last time I tried. I can do gladiator crucible up to wave 60 - though the last two were before I got the nice pants, it should be better now.

Speaking of the pants, the guy that I got them can still two-shot me (with the shots being only split second apart). It's almost like there are two versions of him. First time I managed to kill him in honest fight (honest = I didn't cheat with frozen health, I still think he does cheat), it was inside a cthonian rift, and it didn't even feel that difficult. Some kiting for potion cooldown but OK boss fight, and the reward was the pants shown in screenshot (probably the best combination of prefix/suffix I could wish for, only better thing would be some skills I could use on the base item). Then I met him outside of that rift, and just surviving was almost impossible, let alone doing some damage. But after some reading, I'm not the only one who thinks he's dirty cheater.

And what do you do with your char once he can roll on ultimate ?
The fun of this game is to build the char not to have the more powerfull one.
If you want the best gear, just get an cheat editor and spawn best legendary items : done .D

Aren't you refuting yourself with this? The fun part is building the char... so use character editor to cut it as short as possible? I'm afraid I don't follow your logic, but if it makes you feel happy, you are free to do anything you like.

He killed me very quickly at level 85 but by level 97 or 98 I was able to handle him no trouble, and my character is vastly worse than yours, with less OA and only ~14k sheet DPS. Could just be that his weakness is pure tanks (I play a Battlemage) I suppose, but as long as you don't sit around to eat his attacks the animation should give you enough time to kite a bit.

I'm *really* bad at action games, so it's not a skill thing. Just don't try to facetank him if you don't have a bunch of invulnerability options. Between Soldier and Arcanist, you can have like 20-25% uptime of effective immortality, which helps.

EDIT: Yes, of course I mean killed him on Ultimate. It would be no challenge to kill him on a lower difficulty at 97 or 98 ;)

I'm tweaking stuff all the time, so I may have sacrificed too much DA between the attempts and he can now crit me reliably... it's only a theory, when he's around I don't have enough attention left to read messages :) As for the suggestion, it's hard for melee char to not facetank enemies. Only other option I have right now is kiting + blitz. He has several nasty tricks he uses only at range though, I'm not sure such tactics would improve my chances - and blitz damage is very slow compared to melee.
