I checked your profile. Depending your elite kills, I guess you may have tight budget (like me :D).
I suggest you may try some more defensive gear, rather than offensive gears, simply because defensive gears are much cheaper than offensive gears (as long as you have enough cri).
Life steal passive is not so good for you because your dps is low. You may try adding armor passive.
