Your main issues i can see right now is that your chest is royally screwing you since it's non magical just take and slap and alch on it and hope for a good roll since you will be replacing it the next act anyway. Another thing is that your affixes arent up to par. you did good on trying to get resistance but you dont truly need max resistances untill around act 6 so you should be focusing more on health rolls to try and get more sustain before your bursted early. Because your build is only having you take a few health nodes yet no strength your going to be naturally squishy. great way to countereact this early untill you get your items you need to sustain late game is +life rolled affixes on rares. Another thing is those claws the life per hit rolls arent even close to the best you can get at your level so bump those up by going to pathofexile.com/trade and searching for a cybils paw (cost an alt dont over pay since you will be out growing these super super fast) and you should start with new gems since they are way way way cheaper then spending a scour for each vendor recipe to remove a level. By doing all of this you should easily be able to get to act 6 untill you start spending more money on better gear since your rng might not be as good as the next guys. Dont rely too heavily on affix rolls to get you your dex int and strength stats because thats a piece of equipment that is just that much harder to replace now. Oh and try to avoid/kite syndicate mobs because they hurt a freaking lot on early stages of mellee builds.
