1. Re: Soulswap: I know the Summonstone guide talks about using it with the glyph. I've messed around with that and I find almost no benefit to ever using Soulswap if you are spec'd into Soulburn: Haunt. You will definitely want those shards to keep 100% uptime on SB:H.
2. Re: Opener: It basically comes down to BL on pull or not. If you get BL on pull, I would recommend using SB:SS to get your DoTs up because between BL and DSx2 there's a really, really good chance that you're going to regenerate the shards to get up your next SB:H with <9s on Haunting Spirits.
3. Re: 3 Shards: You only want to re-cast SB:H when there is <9s remaining on your Haunting Spirits buff so it benefits from Pandemic. It's important to differentiate between the Huant debuff (lasts 10s on your target) and the Haunting Spirits buff (lasts 30s on you). The Haunt debuff gets applied when your Haunt spell lands on the target so you have to take travel time into account. The Haunting Spirits buff gets applied when you cast it. It's also important to note that SB:H actually applies the Haunt debuff AND your Haunting Spirits buff. The other thing to take into account is the double Nightfall proc we've been experiencing, that nobody can seem to figure out the reason for (though it seems to be narrowed down to the Draenor empowered abilities if I recall correctly), which sometimes refunds 2 shards for a single Nightfall proc. Therefore, in my view, you should cast Haunt whenever you have 3 shards so as not to waste the potential of a double Nightfall proc. The other "advanced" skill here would be to extend Haunt via Pandemic with the use of your 3rd shard (i.e. Try to extend the current Haunt on the target with your next Haunt cast - not always possible but when the opportunity presents itself, really important).
4. Re: Mutli-Target: I don't know where I'm getting this in my mind, but I seem to recall the number 4 floating around my head - in that you can DoT up 4 targets (if you're using SB:H). Personally I find maintaining DoTs on 3 targets (i.e. Maidens) a nightmare. So if you're in that situation, maybe you're thinking of playing another spec or using Cataclysm. Regarding "Prolonged 2 Targets SB:H", no you do not want to cast SB:H on both targets. Just cast SB:H on the target you're going to Drain Soul from - it's still going to apply the Haunting Spirits buff to you for 30s and the Haunt debuff on the target - and try to keep Haunt rolling on that target with 3+ shards.
