Can you consider haveing hazardous envirements areas/objects?

You know when your on a map and your fighting that there are some areas that you DON'T want to venture to, because of the risk of injury or death.

Let me just list a example as it will make more sense.

Spiked pits/general staked ground: placed in the map to benefit defenders. Here fall damage is greatly accelerated. Running hurts, and walking is preferred. may be found around gates, act as harassing terrain, exa. Use would be potentially to kick a person into there, and a counter to cavalry.

Bridges (with possibly no rails/safety precautions) and dangerous mountain roads next to vary steep, and obviously deadly, cliffs: These could be good choke points to add, and I'm sure having a 12v12 encounter where players can knock each other off cliffs would be enjoyable, or at least make players paranoid of falling. And no new coding!!!

Dangerous rivers: Could be as simple as a bridge over one of these roaring rapids could give players plenty to amuse themselves with. Find yourself kicked into rocky waters? prepare to ragdoll and be swept down the river. Would feel great to watch your opponent die like that. Seeing him bob and crack satisfyingly on rocks. Obviously late in development, but I feel would add great to the general environment.

Hot springs (maybe acidic at times) and geysers: Battles do not exclude natural wonders as there takeingplace. Battles are fought regardless the natural area is hostile to life, or does it worry to mar it. I'm thinking a slightly hilly rocky plain where several of these wonders are about dotting the landscape, with a few fences and small signs of human influence. Shame on the knight that falls into one of these boiling furnaces, while undoubtedly adding a surreal environment to a battleground will add variety, but it will also add wonder. Having a map where these are present with there neat colors and appearance of the waters should surely fascinate a few unfortunate souls. Obviously late development, but nether less, eye catching.

Flames: Fancy even walking through a flaming village is dangerous, but fighting among while it's all burning down? bad situation! Sure, they don't have to spread, but surely a villager, pinned by a fallen bean and hay, burning should send a clear message that yes, this place is under sedge, and second, maybe I should not touch that. Placing them on roofs and alongside general areas should do a lot to atmosphere, especially if they provide the lighting as the battle wages through the night.

Wildlife: Though I doubt we will be seeing many of these creatures on the battlefield, surely out and about in general peaceful areas could be a thing, especially in areas where players are free to explore the general map. I feel bears and wolves in the far reaches of the lobby would not be a bad thing.

General traps: Though I believe your going to add these to finished castle sedges, just a reminder here. Another note, maybe a hunter abandoned his trap in the woods when the soldiers appeared in the area?

Lava, or magma, maybe volcanic elements to maps: Though far fetched in implication, undoubtedly these do exist in our natural environment. So if you have free time and a imagination, I'm sure you can make a interesting encounter, area, or disaster zone. Lets say a actual 100v100 battle takes place, it might chose a vary peculiar map. Think of fighting next to a volcano in some ruins while brimstone is raining from the sky, epic isn't it? The sky is red and smells of ash, to the sides lava is slowly enclosing on our position, and as the gods will, me must prevail! Though I'll forgive you if you don't implement... but if you have free time.....

Sure there is more to comment or suggest about, but there is the general idea. I believe it should not always be the foe that you worry about....
