You are in great need of higher armor and resists, so you can survive at higher MP. I'm not sure what your overall APS is but you want to aim for 2.5 APS at least, or 2.73 APS since you have a Chanto MH. I'd replace your Andy's Visage with a Storm Crow for extra LoH, plus the APoC means you can swap your OH for a Chanto OH without APoC. If you don't already, I'd drop the hellfire ring for a rare ring with 4-5% crit and 8-9% IAS, or pick up a nat's ring with all resist and int and swap your boots to nat's for the 2pc 7% crit bonus, though that might be expensive depending on your budget. Overall you'll need 66% IAS on gear to reach 2.73 with your wand, so keep that in mind when upgrading to IAS pieces. You only need 52% for 2.5 APS, which should be really easy to reach with a chanto 2 pc, if you want to aim for that first.
For MP5 I recommend something like 550 resists and 3500 armor while using Storm Armor - Shocking Aspect. You're welcome to try with lower armor. Since they changed RD it's not as much an issue for CMWW so those requirements are likely a little on the high side, though Electric mobs still hurt, and most of the other affixes out there can still kill if you're not careful.
OK I upgraded what I could with the gold I had. Could you take a look and see how I did?
