Walls are really what you need to slow down the enemy’s early attacks and grow your base, not to make the game loose and to stack barricades on all map.
It could only be used as a means of defending your base in an opponent’s early rush or a surprise attack to destroy the economy in a late game, and to negate the removal of the pillars, I have a suggestion.
- Grants destruction XP to walls. Instead, construction XP should not be granted.
- Walls will instantly spawn with 1 HP as soon as a build order is given.
