Grouping isn't required to level no, but it IS required to do any of the end game content. Dungions like Molten Core, Blackwing Lair, and AQ require well organized groups of about 40 people. This is where good guild structuring comes into play. In WoW it seems the thing is you level to 60 mostly solo, learn what the hell your doing with your class, then if your lucky you can do end game content with a guild.
