I'd go with - who cares?
It is a free CCG that came out 2 years ago. Did you actually expect this to get 100+ posts?
Charge is the only interesting change imo. They made it less, but also do less. Removing the +2 is one thing, but not being able to attack the hero is another. I think that is one step too far.
In case you haven't been following, Hearthstone is actually a pretty big deal in the gaming world. It is quite strange that it doesn't get discussed much on these forums, but I suspect that's because the game is not on consoles.
I love the change to Charge. That card is the reason the horrible non-interactive combo warrior existed and this will surely be the death of that version. No more unfair OTK.
The other changes seem nice too. Execute nerf was long overdue in my opinion.
Too bad there's no change to the 4 mana 7/7 though... Also, screw N'Zoth.
