As someone in the opposition of yourself, I've always dps'd in PVP and I am gearing for heals, I strongly agree. I think Blizzard is most definitely going in the wrong direction with less casts on the move and less instant casts. Blizzard is taking the most under-appreciated and difficult role in the game and making it even more thankless and difficult.
Plus, I also agree leveling is simply going through the motions now. Part of it is being stacked with Heirlooms, but part of it is also the rinse and repeat a few too many times.
