While I can't disagree with you, I believe in the post what I am trying to explain is that Dragonite IS physically bulkier than Salamence on the Bulky Dragon Dance set because it is less susceptable to revenge kills. That Scizor switching in to BP you after you killed something is going to hit your Salamence that you just posted quite a bit harder than it will Dragonite. This is a misconception about Intimidate. It is NOT a permanant defense boost, hence why I never mentioned that Dragonite should be switching in on and countering physical threats and why I specifically said to remove countering Lucario / fighters from the equation. But in terms of overall defensive bulk, Dragonite is still bulkier than Salamence and there is no disputing that. Intimidate is a one-time thing to allow Salamence to switch in easier, that is all.
When talking about surviving revenge kills, it is interesting that giving that dragonite 80 defense evs in addition to it's hp evs give it just over an 18% chance at surviving an adamant, max attack, LO mamoswine ice shard. Of course, 18% is still very low, and it has to be at full health, but a chance to survive such an attach at all is certainly something that is impressive.
Salamence takes about 18% more from scizor bullet punches with minimum investments.
Looking at the bulky sets, after moving salamence's 11 extra attack points over to defense, cb scizor would do 49%-57.8% to salamence and about 45%-53% to dragonite.
They don't have leftovers, so both will be 2hkoed, but it does suggest a much better ability to resist being revenge killed in such a manner.
From max attack LO luke extreme speed:
Salamence (with the extra attack evs moved to defense): 33.5-39.6%
Dragonite: 30.9-36.1%
With dragonite it would be a little less investment, if you ignore life orb, to push that to a 4hko.
Only testing would reveal how important these numbers are, but the difference doesn't appear all to great, although there may be a lot of situations in which the differene could make a large impact. Especially in regards to a pokemon with recovery (roost).
