Spellwarding does not drop your threat (unlike blessing of protection, and divine shield) and just prevents further applications of any magical debuff (as you are immune to it - e.g. Necrotic on M+) - Note: You can use Divine Shield and then taunt and retain threat on a single mob.
Not aware of any stack drops on Augur but personally I haven't tried if i'm being honest, but for negligible magic effects Divine Shield usually works to remove them with a /cancelaura thrown in the macro so you just press it twice, and same for Blessing of Protection for Physical effects that are negligible.
Tichondrius, personally i'd stick without Spellwarding here as the bloods fixate on you and if you are immune to their (physical) dmg you can keep them on the boss as they wont heal (increasing raid dps). So you can Divine Shield/BoP/Guardian+Active Mit to keep them on the boss for more DPS.

1) Prydaz + Chain for raiding. Chain is up there as your self heal's become Lay on Hands during this time, and it's got alright stats on it too (and doesn't conflict with tier) and you get the added bonus of more DPS (which should line up with Seraphim/Potion etc).
2)Raven + Chrono if those are your only options ("DPS" trinkets are usually better this tier than "Tanking" ones, and also a solid stat stick would be better than your alternative options here). The Dagger is pretty shit (and from my experience, has very questionable internal calculations on if it will save you or not) as it's got a 6min CD and a questionable stat on it.
Raven is the best of a bad bunch that you have there tbh.
