yeah i survive mp2 ok, but i have the feeling it's a bit slow, so i am looking for upgrades mainly on the dps side without sacrificing too much survivability. my aim is not only to grind paragon as fast as possible but to upgrade my gear as good as i can
Inna's Temperance with a STR roll. Automatic 1%CH + the awesome 12% Movement Speed, you can make up for the RESall loss by picking up a nice Vile Ward.
Honestly though the biggest hindrance is your hellfire ring. That slot could have CHC, CHD and %AS. So unless you want to sacrifice your 35%exp bonus it is going to be EXPENSIVE to see some real progress.
You can get a nice 250+ str Vile Ward for 4-5 mill, an amulet upgrade for the same price and I advice you gear up your enchantress, use 42 int gems on her, get an amulet with 250 int + socket, rings with 150 int + socket. Don't know why it's slow for you. Not enough LoH or Life Steal holding you back by forcing you defensive perhaps.
