1.Building returns based on specific building types on SS/PS are a great addition, but like I told you before you have added them in the wrong place or something so they are actually too stringent currently. For more info on this see our previous conversation about it. The specific building limitation for ABs/BRs should be based on total buildings instead but I dont think 10% is at all as stringent as it needs to be. Im not a fan of the flat 10% either way especially for BR/AB since ABs will be hurt more by this than will BRs as their base % is higher.
Consider shifting AB/BR to a Constant%*Modifiers*Min(Target_buildings,Attacker_Total_buildings) so that the attack type, MStrat and government bonus still apply.

2. The war portion of the game is more interested with a restart bonus imo. I think walling needs to be less powerful in general but what you are suggesting is my least favourite way to nerf it. If its all we are getting its better than nothing tho.
I prefer;
+attack specific DR, that goes away upon taking an ingame action and has a 1hr reset time(no halflife mechanic), that makes a straight GS or BR kill on a non-waller cost 20-100 more hits than today. This will still be viable for many targets but alternatives will be better by comparison, could be that we see more combined GS/BR, BR/CM or GS/CM kills as well as more maiming and offline kill runs(as they get impacted less).
+SDI loss 0.5% on a DH missile, Base SDI increased to 10-20%. This will get rid of CM rushes and they will instead be used to complement GS/BR runs.
+Bioterror is changed to kill no population, but 0 pop growth. This will be an option against turn-wallers.
+Restart bonus changed from 20%+0.06%*defends and 50%+0.06%*defends for market goods to
20%+0.05%*defends and 50%+0.03%*defends for market goods. (I think that people should be ecouraged to wall but it should be harder.)
+Spy changes:
Effective spal for calculations of spy op success becomes
SPAL=Spies*Acres^(-1/2)
AND
Cause Dissention
3% of troops instead of 4%
This was widely agreed on in the thread that discussed it in the UI forum:
https://www.earthempires.com/...ussion-47479?t=1566674084
Result: Walling will be harder, and allow more counterplay as well as be slightly less powerful in general. Offline kills, hybrid kills and maiming will be comparatively stronger because fast kills are nerfed slightly. Fast kills are still viable, and in many situations they are the best option, but they are more costly and take slightly longer which hopefully allows for more complexion in warfare than the endless strings of GS we normally see.

3. Not sure this is necessary if the restart bonus is re-enabled in some shape or form. But I see no reason not to.
