At the current time, the Blissey analysis advocates that players use a 252 HP / 252 Def Bold spread on their Blisseys, rather than the 252 Def / 216 SpD spread of a few years back. As I've never understood the discussion to be black and white, I looked to the analysis for information. This is all that is provided.
I do not believe this is nearly enough information for a battler to make an informed, concrete decision on an EV spread. Personally, I've often leaned toward Special Defense investment in my Blisseys, but there are undoubtedly far more good reasons than "Blissey needs all the Defense she can get!" and "Scarftar can 2HKO with Stone Miss!"
So basically, I want to discuss the pros and cons of both Blissey's Calm and Bold spreads, with specific damage calculations being provided to prove the "necessity" of one or the other in situations that matter for Blissey. Using the discussion, I would like to write a detailed subsection on the EV issue in general, rather than just listing Bold everywhere and listing some token physical attacks that do more to it when it's Calm than otherwise.
(As an aside: Adding 252 HP EVs only adds about ~5% over 0 HP EVs to Blissey's physical bulk. Perhaps even a 0 / 252 / 252 Bold Spread is worth discussing?

While a Bold nature is recommended on Blissey, a Calm nature with 24 HP / 252 Def / 232 SpD EVs is still viable due to the larger overall defenses gained from Blissey's massive HP. The 24 HP EVs are to achieve a Leftovers number. This spread does cause Blissey to be 2HKOed by attacks such as Swampert's Earthquake and Choice Scarf Tyranitar's Stone Edge, but allows Blissey to avoid being 2HKOed by the likes of Choice Specs Lucario's Aura Sphere or a Flash Fire boosted Fire Blast from Choice Specs Heatran.

To start off pros for Calm:
- Bold and 252 HP EVs versus Calm and 0 HP EVs only makes Blissey take physical hits ~15% better
- Calm and 216 versus Bold and 0 allows Blissey to take special hits ~20% better
- Because of the dramatic difference, Calm would be preferred unless Bold gave Blissey specific survivability, since Calm is a lot better at what Blissey intends to do. This is not a cut and dry thing though; with Pursuit, defensive attackers, and other pests, there may be non trivial damage increases that matter in battle. That's where you come in!
