The changes are good, no question. However please do yourself a favour and don't invest to much into a card game until you have sorted your finances out. Bad financial situation can easily snowball and than take decades to recover.
If the changes are as good as it seams I and many other will pre-order. You don't need to save Blizzard yourself ;).
