Dear Myrthos,
As I understood from the collective interviews up to date, is that within the geographical landscape of <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> there will be a *Finite* number of battlefield-portals from which one could access a battlefield.
When we enter a battlefield for the first time, it is randomly generated but it stays “as a layout” fixed to that configuration when that battlefield is accessed through the same portal.
This means that what remain constant after random generation is the static objects such as floor, walls, roofs, trees, rocks, boxes and items.
On the other hand, if there was no new challenge every time you *Revisit* that battlefield then there would be no sense in saying that you can revisit BF as many times as you wish to level up, and this means that re-spawning competitors or enemies is a must or else there would be no meaning in revisiting for levelling up.
I am saying this because I already saw the full feature of this idea in Knight Shift and they do not even use portals but rather generate the battlefields randomly at game start and that is it, but re-spawning enemies is a logical feature of the concept of a battlefield.
In Divinity, the concept was quite different by placing all the enemies (you need to level up by fighting) on a horizontal-spatial-scale rather than on a vertical-time-scale.
Random BF generation is a matter of beauty and tactics of natural features of the placements of the objects.
Spawning enemies in those battlefields is a “per-visit” triggerable event independent of the idea of random generation.
Kindest regards.
