if you're gonna keep away from wagner i think i'll give it a shot 
Yeah, go ahead. I haven't touched anything since I remade the Alamo. Though someone edited my Hampton Roads, I had to put back to the original on the DA server. Someone decided a cannon on the only bridge that is also destructable was a good idea, along with a ton of spikes and dirt around the flag that any good sapper would build there anyway...
in my opinion a good NaS siege shouldn't consist of towering walls or large forts like NW's do though you were talking about choke points and not towering walls and one of the specialties of wagner is that it will probably be a pretty aggressive siege
Yeah, I'm not a fan of the same star fort prop everyone uses over and over. You'll see a bunch of lazily made custom maps because people don't want to be creative and spend the time on them. A good map takes weeks of editing. Cannons can also ruin a map if not done right. Whether they can hit a spawn point or glitch through certain walls. Thats why most of these boat maps are almost unplayable because boats full of people get blown up left and right and boats don't respawn fast enough.
*edit*
Also keep in mind, sieges are almost always lost by defenders in real life. No one would sacrifice their army if they thought they would lose. Sometimes they would just starve them out. Successfully defending on siege should be almost like a survival mode. Make it as far as you can and inflict the most damage on attackers. Victories should be few and far between for defenders.
