Push for 2.8 ww break point with current setup by looking for more attack speed from a new ring, Crafted Gloves and Crafted Amulet. Not an easy task by any means.
I can tell you 2.86 w/ SoJ is no easy task. The only reason I made the jump is because I told myself I would if I ever crafted a neck that could help sustain it. That is the only reason. If I never got a trifecta neck (still trying to craft better ones), I wouldn't have done it.
I am glad I made that choice, but it is very easy to reach the 2.86 BP inefficiently. Hell even my set still has a bit of inefficiency due to non high crit rolls on certain gear. I'm working to fix that...but it's all part of the process.
I totaly agree with Gill on the recommendation to upgrade the IK chest. Yours is pretty much a starter chest which you technically should have graduated from a while ago.
If you do decide to go to the 2.86 BP, you need 59% IAS on gear combined with your current .24 EF.
Good luck in your gearing! :)
P.S. Craft shoulders of vitality...not strength! ;)
