Here is super in-depth info on break points

tl:dr; sheet dps doesn't really mean shit
Here is my understanding of it:
Increasing your other stats in between break points is really flat. When you increase your attacks per second past a break point you'll see huge jumps in effective DPS. I think the APS most people try to get is 2.50001 APS (2.14 APS unbuffed). You're very close to it; I think you need 12 more ASI total. (Lacunis + ASI on ring or amulet would be cheapest)
Too lazy to do math but you're probably buffed into the first bracket or the second bracket.
Moving to 2.5APS will increase your WW damage 15-30% which is pretty significant.
edit: you can click skills on in d3up. I just checked and you're 2.3635 aps w/ WotB

The other build you can try is switch to HOTA/WW. I think it's the most versatile/overpowered build right now.
The "spin up" time sucks but once you get the initial 20 fury for battle rage you should be set for the rest of the game. The build is great IMO because once you get down to 1-2 targets as regular WW you kind of get boned. You have to kite to pull in more trash to maintain fury or risk running out of WotB. If you're running hota, however, you can switch to super high dps single target attacks to finish off elites while keeping permawrath (so fuckin overpowered lol). One of the nice things about HOTA is that sitting right under a breakpoint isn't as much of a deal breaker because any attack speed you have will increase the speed at which you attack which means your sheet is more representative of the effective dps you're putting out.

The third build you can try is switching to 2H. I think you only need to hit the 1.18 aps breakpoint which you'll hit easily? with the gear you have and a skorn.
