Modifiers aren't exactly seen as a blocker, they should be weighted. When the path is too long, modifiers can no longer block enemies. When there are too many modifiers, the enemy will go directly from the route with few towers, and the towers will not be able to block the enemy.

Cinex : your screenshot is unfortunately too cropped, enemies may not have other choice due to barrier I guess but it's hard to tell with only this part of the map.

Try it out for yourself, modifiers are now weighted. When the length of the road is greater than a certain value, it will exceed the weight of the individual modifiers, and the modifiers will no longer be able to block enemies. If there are too many modifiers, the weight of a single tower will be exceeded, and the tower will no longer be able to block enemies.

Got trolled by the fullscreen bug, here's a better screenshot.
