Now I understand where you're playing. It seems to be more difficult there than on the South or North surfaces. Not only that, but you constantly encounter either Mages, Druids, or Vampires... I don't know why, maybe it's a bug. Or perhaps it's designed that way, so that players using the Dungeon faction will play as Dark Elves, for whom defeating Druids and Mages isn't as critical.
And the speed is much lower (if you take Haggeesh). It's faster with Argath, but if you have ranged attacks against stone and wood, you might have problems.
I still can't understand why your level is so low...
With all the problems, by the end of the second month, I was already at level 20, with 20 defense and 20 attack, and I played three times... I didn't fully explore the surface, I didn't clear the map completely (in the Dungeon), I only took the Dragon Utopia... I didn't visit the trees... It seems that the lack of Logistics is causing your leveling problems... I'm talking about Orcs.
You're probably right, but I don't take Logistics because there's no room for it in my build.
My advice to you is to play this map with a human opponent; in my opinion, it's the most interesting map for Multiplayer, and I choose the green faction (at the top right) because it's the most difficult to start with – and that's what makes it more interesting!
