Tactics for playing as the Dwarves.

Here are a few pressing questions:
How to defeat a Logistics-focused player on large/medium maps (like in "Armageddon's Blade") – against Elves, Humans, Orcs, or Necromancers? They simply sweep through everything (especially with Vittorio or Argath/Hagesh).
With Dwarves, I can't manage to capture enough artifacts, so the opponent ends up fully equipped (and their army is practically brand new). Both of them run around with several units of archers + a tent and a ballista, and they don't care about anything. (It's a silly question, but it's getting annoying.)

And another thing: on the "Underground Treasures" map, no matter what I try, Hafiz always develops first, breaks through to the sea in the first week, and by week 3, he's already attacking other lands. If I choose machines for the Dwarf, I only take a tent because a mage will immediately negate the ballista's effectiveness.
I usually practice (if I can develop relatively quickly) a light-based tactic, with mass evasion in particular. I can't decide which hero to use: Inga or Karli. Inga because of her education and eye skills. Karli, well, it's obvious why.
I've only managed to kill the mage a few times, and that's only because he made mistakes and didn't develop his Hurricane skill (so he just runs back and forth... or something).

Joy, if it were as easy as you say... but what if there's no tent or rune energy, and you're up against forest archers or druids/archmages?
