You're better off starting your "nuke" a few seconds earlier around 3.7 embers; with the crit from dark soul and any other buffs you have up, chances are you'll make up the .3 ember difference while you're casting the first three chaos bolts.
Refreshing Immolate at 4-4.5 seconds is fine and exactly when you should be doing it. As far as refreshing it during your burst phase, I'm torn on that sometimes. With fewer big procs at this gear level to rely on and fewer times to dump embers, there are situations where I'll let Immolate sit off for a *very* small amount of time if it means squeezing one more Chaos Bolt out during my Dark Soul. basically if I have the choice of letting immolate sit off for two seconds or getting a Chaos Bolt out with Dark Soul, I'll take the CB and put the immolate up immediately afterwards.
The AD talent works with the Dark Soul now and I really love it at the moment. With the glyph, the reduced duration Dark Soul is just enough to get four chaos bolts with, and that's really all you need. Try a run with both the glyph and talent for Dark Soul and it literally feels like it is *always* up. Try it out once and let me know what you think.
