I would love to see a modifier that lifts the class limits.

This modifier would be called Angels of Death and it would lift the class limits for PvE, allowing players to have any class combination without conflicts. I think this would the best way to remove the class limitations, by having it as a modifier for stratagems. They can make where no perks or abilities stack. I always wanted to have a team of 3 bulwarks so I can roleplay as a bladeguard veteran squad. If you play in private with this modifier, the bots will spawn in any random combination of classes.
