There are interesting mechanics in 5e that I found interesting to use in a future BG game: The landscape-related ones. "Difficult terrain" and "Cover"

https://roll20.net/compendium/dnd5e/Movement#toc_3 Difficult terrain is related to weather.
Since in DoS games you are able to use the terrain and weather as a weapon, it would be cool if they implement those.
Cover was also used in RT strategy games like Warhammer 40K so it would be no problem to use it in RTwP or TB. Games like Pathfinder used the difficult terrain feature and some cool weather effects that give penalties.
Larian does not have those features confirmed in any interview I know of. We have to wait until the next interview with Swen "Spoiler-free" Vincke, but sign me in for this.
