I have to disagree with you. The changes to fanatsy didnt neccesarily balance the game. it made it more random which takes the skill out of the game. It dnt balance the armies it just changed which armies are more powerful and nerfed others some it made worse. For example the magic phase made high elves stupid broken and orks and goblins are pathetic. Dwarves got better but vampire counts and chaos warriors got worse. The net effect is that it did change things but by making it more random it made it more fun forv some and less fun for others.
The things that you listed are for the most part changes that are not from fantasy and I am not necessarily opposed to them. Most of them dont seem to come from Fantasy so i guess that is why the dont seem offensive to me.
In responce to your intent i didnt see 5th ed as really broken. So cant really see anything as needing fixed rules wise. The probelem is within the codices not the rules. i dont see the rules changing that.
