4th edition Dungeons and Dragons review

When I heard the 4th edition of dungeons and dragons came out, I was wondering what would happen to 3.5. I expected it to be bad, but I hoped I was wrong. Early on, I disliked what the design team was coming up with. They apparently were going to focus on bringing in new players, mostly those who were into hack and slash and who favor computer games. The things they said that they were excluding from the core rulebooks upset me. If you're going to bring them back anyway, what's the point in excluding them? The classes removed are barbarian, bard, druid, monk, and sorcerer.
Once the book came out, I looked into it. I was shocked. I thought it was going to be bad, but what I saw completly disarmed me. I will explain what I mean.
For starters, let's take a look at the races. They removed gnomes from the core races and instead included Tieflings for those who want to play a bad boy badass like many of you do for some reason, and dragonborn, which are dragonpeople. Each of these races have no drawback and a racial power that grants a special ability that's often broken. The dragonborn for example, has it's racial power be the ability to breath poison, fire, lightning etc. like a dragon. That's way to powerful. Other races have similar traits, and NONE of them have any balancing features. Also races such as the half elf have ability scores that make no sense. Half elves have a +2 bonus to constitution. Why? Is there a particular reason why Half elves are somehow tougher than other races? I consulted this with my friend (who is an avid 4th edition freak) and he said that constitution measures the ability to survive. When I asked him to elaborate he said the ability to survive dangers. Of course in a fantasy setting that's similar to the medival times, regular people face droughts, wild monsters, the plague and other dangers that could potentially kill them. Adventurers face dangers in their career (duh). It's completly natural. Those who die couldn't survive . Does that mean that all dead adventurers have bad constitution scores? No! Some of them actually had great constitution scores. The fact that they died has nothing to do with their ability scores. But I'm getting ahead of myself.
I'll post more on this later.
