you need more AR and you should try to get a wand with either 1.65 aps and a socket, or IAS (enough to bring it to 1.75 or more aps)
For AR you should either get new gloves with cc, IAS, and 70 AR, or a tals chest with AR. Your boots also have quite low AR so consider getting ice climbers or if you can afford to get nat's ring get nat's boots with high int (and possibly bit too if possible) - the nats set will give you more cc while ice climbers offer much higher mitigation. since your cc is pretty low (aim for 55cc or more) I'd recommend nats 2-piece boots and ring, but the ring can be quite expensive (on the ring you want cc + AR or cc + int or AR + cd, or some combination of that sort depending on what you can afford and what stats you need the most. Since you're AR is quite low I would recomend AR + cc or as a less expensive alternative AR + cd).
Getting a 1.1k+ dps IAS chant's wand with 1.75 aps or more (max is 1.79 aps) should allow you to hopefully drop your inna's pants so that you can use rare pants with much higher mitigation stats such as 2 sockets, 70 AR, 150-200 vit, 90+ int, and 700-800 armor.
your source is also very low damage. getting a chants source with 350+ damage (with the lower end of the damage being as high we possible) will give you a large dps boost.
right now you are using energy armor and crystal shell - your goal should be to get your AR and Armor high enough that you can switch to sns build (storm armor shocking aspect rune and diamond skin diamond shards rune) which will do a LOT more damage in combat If I remember correctly sns multiplies your sheet dps by about x8 so 100k sheet dps will translate to about 800k in combat dps. For SNS you will need around 900-1k LoH as well.
take a look at aimless's profile, he tends to balance high mitigation, high cc and IAS, while maintaining high dps quite well.
as for me, I have my own goals for my next gear upgrades but I'm happy to hear other people's suggestions. Currently planning on upgrading gloves and amulet next, and considering going back to IAS wand so that I can replace lacuni for more mitigation.
