You die as much as I do and see how frustrated you get :P
I was playing the game since Day 3 (I bought it Day 1 and waited 2 days for the server crap to calm down) and I KNOW what it's like to be killed a lot. And my wizard had your problems... until I played as my barb more when Paragon Levels came out and I started to solve my gear problems. Now I have a Wizard who has a build and equip setup to do what I like on mp7/8 (my goal anyways, mp10 I have a barb for that): Melee Combat.
Your primary problem is this: You lack organization.
You have a build that looks like you were playing Public games all the time and it has no uniformity. At least with WW/CM, Spectral Blade or Archon, all the skills work in unison and provide the player with their purpose: Destroy monsters as efficiently as possible and minimize the weaknesses.
The gear problems are as follows:
- You are using Chantodos but no WW/CM
- You are using a crud ring set when a Hellfire Ring and Zuni's Ring with CC/CD/IAS can solve the problem. The Hellfire Ring can be made for free at least.
- You could make crafts better than the gloves.
- Your Tal's amulet has no CC
- You could probably craft better shoulder pads for a higher AR score.
- A few of the items you have are BiS but are of poor quality (the belt comes to mind)
And I have a saying: The DPS of a corpse is 0. No matter how high that number is alive, it means nothing if you get slain all the time.
Solve your EHP problem first and recharge your funds. Then you can get some better quality BiS items. Hell, you might even get some items as you play.
Also, don't just aim for mp10 and say "THATS MY GOAL!". Take it one step at a time and try to rise up the mpX dosage so you can handle it. Going straight for MP10 will either lead to disaster without a game plan or you would end up purchasing items on the GAH (or worse RMAH) that you could have either gotten off an enemy for free or with currency you may never replace for a long time. I for instance aim for mp7/8. It has a nice balance of difficulty, speed and rewards. If I can do mp10 (which so far my barb can), then it's a bonus.
If you want to give up, then do it. But know this: It will be your own fault for doing it. Not the game's, not the character's, not some higher power like the angels. Because you had the chance to fix this easily fixable problem, but you chose to hinder yourself.
