Well it seems u kinda crafted items and just ran into the instances.. I think that you will need to build up ur gear more (not by just running around in alll the heroics), but by doing normal/heroic vault. Going to naxx, where there are other geared people so you can pick up some sick items.. Get some gold, and put the best enchants on ur items... For me, I run a mixture of pvp items quite a while. Do you have any interest in pvp? maybe just get some gear in there to fill the gaps of blues or w/e that you cant yet obtain in the heroics...

Thats my way I would do it..
