Bring back ladders in Battle, make them unbreakable.
This would bring in exploits like blocking doors and narrow areas with ladders, so, if possible, add an additional vote option to destroy all equipment on the battle or have certain items that 2h-specced dudes on an enemy team can destroy.
CRPG got very dull and bland after the ladders were removed, it got even duller after the female voices were replaced with some hick teenage girl voice. In order for this mod to gather popularity there needs to be more equipment and features that can diversify the playerbase and how they play.
