Actually Turrets have an Upgrade named Wallmounted Trebuchet
Orcs have Wallmounted Catapult and so on
Walls really need some more Appearance I think
So how about this
Put in a Research that is Named Man the Walls
With this a new Upgrade for Wall Segments and Palisade Towers Becomes Available
This would be
Wall Mounted Archer
Wall Mounted Crossbowmen
Wall Mounted Goblin Prowler
Wall Mounted Ranger
Wall Mounted ..... whatever Units each Race has ^^
Now the Effect would be that upon Buying the Upgrade (which can be bought Parallel to the Arrow Protection Upgrade) 3-5 Archers or whatever Unit was Selectet will be placed on that Wall Segment (number of course depending on Race and Unit 5 Goblins but only 3 Rangers for example)
This would not Only be a Great View but also Justify some more Str Gain from a Stone Wall
The Units on Wall would be like Normal Units with exception that just like Wall Mounted Trebs they have slightly Increased Range to Conter enemy Attacks effectively
The Effectiveness in Combat wont be that Great since even with Whole Wall Upgraded to that the actual Amount of Archers would be maybe 10 squads which cant change Position and not Assume Formations or other Special Actions
but for Support of other Units and most of all for the Gameplay Feeling in Town PvP this would Great
