I'll admit up front that I'm not terribly good at pulling useful information out of WoL compared to WMO. Just a matter of what you're used to, I suppose, but I wanted to admit the margin for error before I started in.
Pulling the following from attempt number six in your logs, since it was the longest fight, and thus (hopefully) the best indication of your normal skill usage.
I couldn't find where WoL might track the number of Slam! procs you got, but 27 slams seems slightly high for your fight duration. You probably want to check to make sure you're not using non-proc slams, and that you're not horning in on what should be a WW or BT GCD.
Your BT usage looks about right for the fight length, but you should be able to squeeze in 3-5 more WWs over the course of the fight by cleaning up your rotation.
You may also be able to gain more damage by not holding out for Lust before your second Deathwish, thus gaining time in the fight for a third use. I'm guessing that you guys are holding out either for about the three minute mark, when all personal DPS cooldowns would have been back up, or for the execute phase, neither of which is terribly conducive for us with our two minute cooldown.
Lastly, your HS usage seemed a bit high (47% of all swings), though not much. With all the raid damage going out until the third inhale, rage starvation isn't a huge issue, but you might want to look at moderating your usage slightly during that period to keep up with the needs of WW/BT.
