Here are my stats:

My build:!YUX!ZaZacc

I'm always playing in a group so keeping that in mind, I really need some help. I'm currently getting destroyed by even the normal mobs at the start of the act and there really isn't much I can do which means I'm probably doing something wrong. I know that act 2 is suppose to be brutal, but a point in the right direction would be nice.

For the people who have completed act 2 and beyond, I just want to know what stats I should focus on upgrading and if there's a better build out there. Is there anything I did wrong? Any advice?
