Some sort of Survival Game-mode
There should be a 5-man game mode to where you have to defend a "base" or "keep" from the beasts of Valoran. Kinda like CoD Zombies? There should be health shrines to regen, An item shop in the center, and a variety of monsters/beasts. (This can be a perfect mode to show off the creatures and world of Valoran with in-game play! Focusing on a different type of teamwork, PvE aspects.
Aspects of the Game-mode:
- Survive as long as you can without all your teammates dying
- As the match goes on strong waves of enemies appear
- Add new items specific to this mode
- Can use the "capture" mechanic (the one in dominion) to "patch up" broken barricades or barriers
I believe this type of game-mode would have potential to be a fan favorite.
