This math is why for LH/R1 raids I personally think an incite tank is way better. When I hit intim then follow up up immediately with an Adren/boulders that gets me about 1.5-2 million hate every 9 seconds… usually sufficient however much DPS is out there even with some crazy imbue stuff going on.
Absolutely, hate tanking is a lot more effective (aside from Intim being AoE, which usually doesn't matter for raids).
But generally takes a bit more investment, at least now that like Carrion Swarm is out.
Personally I have a first-life tank/healer that I've tanked thousands of raids on, and it works great with just Intim assuming people manage their threat. If not, squish squish. We do a lot of teaching raids, and it's good teaching XD
There are a lot of better tanks out there than mine, but it's worth knowing how threat works on both sides of the equation.
From my experience "hate tanking" is far far better than "intimi tanking". It's why I'm hyper-focused on your paladin dwarf build which seems to try and straddle both worlds.
I bet in terms of defense and maximum aggro it hits he sweet spot. Maybe. I haven't tried it yet.
If you can, hate tanking is a lot better. I've tanked quite a few lower-difficulty raids on a full-DPS toon, and as long as you can survive it's super easy.
Even at -100% threat standing, Intim gives +400% melee threat for 12s which makes it super easy to hold aggro against everyone else in the raid.
My main has about 100 more lives and 80 more reaper points than my tank though, which definitely helps XD
