Walls and Turrets and Enfilade field of Fire

[Hatsune_Neko]

With the new walls and turrets that are coming out i have noticed something odd.
Now as a kitten of history and war ( i know, strange combo for a female to be involved in ) that the walls allow the bandits or attackers to get right up to the wall. at the base, now as any good strategies would know, you don't want the enemy near the base of your wall, you want to keep them at a distance for your Enfilade and defilading fire can wreck havoc on said enemy, keeping them from your point of defence.

This also causes a issue with in game combat, as the turrets try to literally fire thru the floor because the bandits are sitting at the base of the wall.
Was thinking that maybe something should be added to the front of the walls like a ditch ( Not a Mote ) or pointed logs or even a adjusted sub portion of the wall. ( shown in late English and french castle designs, was used to keep the enemy away from the wall and prevent the wall from being undermined by digging. or slow it down. )

Even though i know the current Pathing engine has issues, but it would be a nice addition to future walls. or maybe extra parts to be built? this would give the gunners time to actually fire as the enemy tries to cross that barrier, to get to said wall and eventually assault it ( when the new pathing AI is added hopefully allowing for that )

or something of a more simple design.
