Yes some additional planning should be required, but there is nothing "Tactical" about a single buff that makes all enemies 50% more damage spongey.
If anyone can show that the AI is different between difficulties, that might be something. But people wanted to fight more difficult AI, not just meat mountains.
Of course it's tactical, your usual one size fits all strip armor and CC to death does not work, that's the whole point of it.
The AI change is right there in that sentence - it gets a chance to actually act before you shut it down and blow it up to smethereens like you can do with 90% of Classic encounters.
