I'm absolutely sure that social gamers need something - a real strength of a class system is that different players with different tastes and different strengths can work together at the same table. And it doesn't take that much work to include the slayer, scout, knight, hunter, and elementalist.
There were two groups here; one group who disliked breaking AEDU - and the other that disliked the return of caster supremacy and the casters getting all the interesting options. This is why I always bring up the pyromancer elementalist here. A caster as simple as a fighter and where "I burn it" is as legitimate as "I hit it".
