What is your opinion on the possibility of introducing a third tier of maps and a new faction into the game?

Negative. How many more "amazing" ideas can there be? The third level is nonsense. Where should the third level be? In the sky? That's absurd. Below the dungeon? Also absurd. The Astral Plane? An unplayable absurdity. A subterranean level is more than enough.

Did you even read the first post? You probably don't realize that you can choose the number of levels in the game. If someone had created a similar thread about the dungeon during the creation of the third "Heroes," you would probably be screaming that it's absurd as well.
