DOW 1 was very macro-intense.
DOW 2 was very micro-intense.
DOW 3 is halfway. You can do all the macro you want, yet when SHTF, unless you micro you will suffer.
Case in point, did a 2v2 last night. My eldar opponent thought it was a good idea to mass ranged infantry with his hero as melee... until I podded down 1 dreadnought and 1 ASM marine. While those got in the fight, 4 ASM + Angelos + Terminator jumped straight in. He brought his banshees out, but I had heavy bolters + lascannon waiting for him. But if his teammate podded down dreadnought it would have broken my back.
Eldars farseers have a lot of support ability that can be game-changing as well IIRC. I lost a few squads to dilation fields.
So I see it as a balance between the two.
