What should be added to the top five from the previous installments?

I think the Veil of Darkness is necessary (at least with a small radius). For example:
The entire map is visible, and you can see all opponents clearly. As soon as something happens, everyone immediately retreats to their castles.
Although, I agree, on a map with many passages, it can be detrimental. Sometimes it's really annoying.
Conclusion: it could be added, but not to all maps (although a poll could be conducted to see how people would react).
