Thats an interesting point. I often refer to this as "you have to commit" to what you're doing. Especially with VC, you have to commit to a unit - you can't just bring 10 ghouls and call it a unit. While there a ton of fun variety throughout the book, your lists are stronger if you pick a few units and make sure to have a lot of bodies in them.
This is also true for your dice rolls. 5+ to hit is actually better than two 6+ to hits. A 5+ save is better than two 6+ saves.
I never thought of this in terms of war machines, but it makes sense. Most armies are comped to one though.
Magic is limited by range and often forward arc and LoS. One of your spells has to provide something relevant in the current situation. You ahve to be able to cast in the current phase (many things can prevent you from doing so). When you cast you need enough dice to cast, and you have to meet the casting value, and it not get dispelled. Adding an additional pre-layer to roll to see what spells you even have is nonsense IMO.
