Is attunement neccessary?

I've been slacking on my blog the last couple of weeks. Mostly because if I'm not working, doing chores being a good husband etc. I am doing the new Heroic Dailies. I am such an Rep Whore it's not even funny, the need to be exalted w a faction can make me into a daily running machine. But hey on fenris we're not even @ 60% of phase II & I'm already revered with SSO.
In the mess that is 2.4 Blizzard removed attunements. While at first I supported them on this change, after experiencing several sunwell pugs with players who don't know their ass from their elbow I have had to change my view on the attunement process. Attunements in the game are necessary, you need to separate the wheat from the chaff, but it needs to be balanced with letting casual players have access to content. Otherwise you get players who cannot complete the content becoming frustrated & frustrating fellow players.
