So when I got to Urzael I was not happy with how long the battle was taking (I was soloing him). I would get bored, then sloppy and then I would get killed. I started with more toughness (and less DPS) that I needed, so I changed my gear up to max out my DPS (while sacrificing lots of toughness). That felt better, but I would die if I made a single mistake or if my latency went to yellow for a moment. So I ended up getting rid of Black Hole Supermassive, and I changed it back to Magic Weapon Force Weapon. I put on most of my toughness gear and I was finally able to beat him.

After I killed him, I continued into the Bloodmarsh and I found that the everything felt perfect! Not too hard or too easy! I could actually live long enough to use all of a pool of reflection bonus. So right now, this is my sweetspot.

I found my first level 70 legendary weapon last night and it was a 2 handed staff. So I had to try to increase my attack speed while trying to keep as much crit chance as possible.

So my Toughness and Healing are lower than before and I have noticed that I am little more squishy. I am still able to kill very quickly and I don't die very often.

I mostly play partnered up with a DH friend so my low DPS isnt that much of a hinderence - also I use exploding palm which has damage that scales with enemy hitpoints rather than player stats which speeds things up even when solo. Also, I haven't died since I hit level 60

Can solo alot stuff on torrent 2 since I changed up my skills, takes time though lol
Tried out torment 3 in a public, did fine just have to make sure their is a real tank in the group :)

I traded in my 2,502 DPS 2 hander from the post above for a 1,990 DPS wand and my old Chantodo Source (I have not found a source that gives me as much DPS). I still have 44.2% increased Attack Speed which means my attack speed is now 2.02. I also have 42% Crit Chance. I tried using my Paragon Points on Crit Chance instead of Attack Speed, but Attack Speed was giving me more DPS.

Due to the auto-adjust of the monsters, Torment 1 still feels right, but I may poke my head into Torment 2 tonight.

Last night I managed to enchant a socket onto my level 70 Starfire wand. It has 2,062.9 DPS and 643 Intel whereas my rare wand had 1,990.1 DPS and 559 Intel. I was also able to enchant a level 70 Source to give it more DPS and Toughness than my pre-patch Chantodo's Force. Here are the stats for my new rare level 70 source:

Sphere Weapon
+284-342 Damage [262-394]
+601 Intel [525-625] Was 500 something Vitality before the enchant.
+9.5% Crit Chance [7-10]%
Crits grant 4 Arcane Power [3-4]
+14 Max Arcane Power [13-14]
