I was one of the first people to be skeptical of the LFR system and what it would do to raiding prestige.
Sometimes I forget that 90% of the playerbase don't have the time to commit to raiding. I found out on friday night at a friends house that his brother with down syndrome did lfr and loved it. It brought a lot of smiles and laughter and he was so excited that he showed my friend the demise of Deathwing.
Ifr really does give players at all levels the oppertunity to see all the content in the game and blizzard should be praised for this feature. Hardcore raiders still get the harder content and still get to epeen with titles until the heroic content is cleared by the rest of the playerbase an expansion later.
