Opinions are not facts. Most of this stuff seems completely unnecessary to me. We’re lucky if we get changes at all, much less a laundry list like this. I’d prefer they focus more on the racial balance, as items are not race specific and everyone has access to any of the items on a map regardless of race, making them “technically” balanced regardless. They need only be balanced against each other- or more specifically, balanced against other items of the same tier- so you would do well to break down your list by tier and describe an item in that tier you think is balanced and argue why the rest of them in that tier are stronger/weaker- your list seems extremely arbitrary, like “i like this item and not that one.”
All I’ll comment on is the runes, the exact values are not really important, 99 times out of 100 you’re just going to click it regardless of what it does, because it’s better than leaving it for your opponent(s) to take. Which isn’t to say that it wouldn’t be nice, but you can find the values if you know where to look, and you probably only even care if you fall into that category in the first place.
Microsoft is not really involved in the development at all. They are the publisher, not the developer. Caring for WC3 remains at a minimum.
