I have an idea so that construction sites and barriers may be once again legalized! Make them completely vulnerable to blunt damage! That way barriers can still protect against archers, and it also gives players another reason to use blunt weapons.
Would make sense imo too, blunt damage being able to crush siege equipment, and that way it removes the problem of people using it to block ramps and walls and etc. The main reason why the equipment is banned is due to it being able to block passages, so we should make them brittle to melee dmg (blunt dmg) to be specific. Also seems like it can give certain players a "role" feeling in battle, such as anti-siege and such.
I really enjoyed siege equipment when it was all released, as it made battles dynamic, and feeling fresh everytime [ : I also think it added a little sauce to those maps where defender/attackers can run in circles and still win most of the time.
OR as suggested, Allow axes to have some trait like, "Bonus to siege equipment."
