Iskar: You're casting very little AoE CBs, compared to what I had, and what Neepeh had as well. It also looks like you weren't able to keep up FnB during the 2nd intermission phase, make sure you've got atleast 3 embers before casting a FnB-CB. You've timed your DS with the intermission phase, which is good for your dps. You are also not using FnB-Immolate during the intermission phases enough. Aim to keep it up most of the time, it does considerable damage, and gives embers back which, in return, give you more FnB-CBs.
Xhul: Shadowburn heaven. Use your havoc A LOT more and cleave SB with it. You only had 32 casts and 39 hits ( meaning you havoc cleaved only 7 SBs ).
Mannoroth: I'm not particularly great on this fight, but the same rules apply here as they do on Xhul. Use havoc and cleave as much as humanly possible, and you actually did a pretty good job at that actually. Because you didn't use your Darksoul at pull though, you missed out on a full darksoul use.
If you're having trouble managing havoc in multitarget fights, I'd suggest setting the target you want to havoc (usually boss) on focus, and get a macro that automaticly casts it at your focus target.
One other issue that I see is that, on all 3 linked logs, your immolate uptime is pretty low, and while I understand it's pretty annoying to keep immolate up on Xhul and Mannoroth, because of the amount of time you have to spend on other adds etc, you should still invest some effort/attention into keeping it rolling on the boss. I personally have a TMW setup that shows me my debuffs on "Boss 1", which is usually the big boss.
Lastly, try and line up DS up with other procs, like your ring, GSR, potion, BL, as much as possible.
