I am once again proposing some BG ideas. They could be brawls for all I care.
CTF in the Boralus Hedge Maze. The walls will LoS and you’ll be able to set up teleports n double jumps n what not. Also have like 5 different iterations of the maze.
Some point capture/SotA type map on the Grimrail. Take carts and fight in boxes. Open sections also available for knockoffs.
