I agree, they seem to evolve the game in the wrong direction. It started with the new design in Mirrodin and than when they introduced planeswalkers I've pretty much stopped playing.
New design started with 8th Edition, actually. I remember because I went out and bought a pack of 8th Ed and thought I'd gotten fakes.
There were some cards with this weird design in Lorwyn that make me want to vomit, it looks like some really gay sci-fi CCG.
The planeswalker concept doesn't bother me so much, but it seems absolutely unnecessary and pointless. Just make the characters legends and don't bother us with this new card type.
EDIT:
On the rule changes
1. Simultaneous mulligans...sure, why not? Just makes life a little simpler.
2. In-play = battlefield. Why not? I've always used cast in my head. Exile I don't like, though. Fuck that. Also, cards are no longer actually removed from the game...unnecessary functional changes are lame. Also, this nerfs the Wishes. "Beginning of the end step" is fine. It actually was a bit confusing before...
3. Nixing mana burn is lame.
4. Changing the token thing isn't a big deal but does kill a couple cool tricks.
5. Combat damage doesn't use the stack...WHAT THE FUCK. This is a huge fuck you to anyone who plays the game seriously, as combat damage using the stack is pretty much key to a lot of tricks and strategies that make the game fun. Fuck this. The way damage dealing works now is also really lame. Why was this necessary?
6. The change to deathtouch isn't a big deal, but it's still lame.
7. I think the change to lifelink is actually good.
