Plague leech will be for single target.
Roiling blood will be for fights where multiple adds are spawned, like on Yorsahj.
Unholy blight will be for aoe fights where there's significantly less adds where a blood boil would do way more damage than a heart strike.

Since i'm thinking of conversion as being a lower Death Pact, will lower CD (although I know it has no CD). Without a doubt conversion will be better in other fights compared to Death Pact. Like in fights where you'll take heavy burst damage every 20 seconds or so. Kinda like on Hagarra, I would love to have conversion for that.
Another example of why i felt the need to go through every talent, since which one you use will depend on the fight and we will probably be switching a lot. This is what blizz was going for with the new trees. I've got Death Pact over corruption in the default raid tanking spec, but that doesn't factor in any mechanics so it is very likely we will see this talent put to use in practice.
