Is it necessary to need 4 levels? When Flex was introduced I coulda kinda see why it was needed to have a 4th, as it was only a trial run so to speak and Blizzard weren't sure how we would take to it and if the mechanics would work well enough. So they introduced Flex instead of putting the flex mechanics into Normal..
But now we know flex works well - do we really need to keep it as a seperate level? What's wrong with LFR(Flex) - Normal (Flex) - Heroic (20man).
Blizzard said originally the idea behind flex wasn't for us to PuG it, but to allow guilds to run together without fear of dropping anyone out. I'm going to pull some figures out my arse and say that flex is predominately ran by PuGs. In the earlier weeks there were many a few odd guild runs here and there, but mostly guilds tend to now be raiding in normal mode.
So who is WoD normal aimed for?
