I have to disagree with your deployment and movement restrictions being a finer degree of refinement. Movement works differently, but as you may have to contend with the opponent having a double turn, or yourself having it, movement and deploymwnt in AOS is more complex, and requires a greater amount of tactics to move properly and effectively. You need to be able to think 3-4 rounds ahead. That being said the more fluid movement does make it easier to come up with new tactics for movement. The restricted movement and reforms had challenges, and required good thoughtful tactics, and was definitely more restricted by terrain choices, but it is no less important in AOS. As someone who has played both, I can tell you for certain that deployment and movement are just as tactically challenging, just in a different way. And if you only like the challenges offered by one that is fine. It is okay to play to your tastes.
Can't argue the magic point. The magic is simplified, and nowhere near as complex or tactically important as it used to be. There will still be make or break magic spells in some games, but not to the extent it was in 8th or end times.
