If you can't enjoy a party without taking pills, you should probably question why you're going in the first place.
I mean I love my E as much as the next dude, but I enjoy the scene for what it is without the drugs, and if I didn't I'd probably have a much better time getting wasted at house parties or commercial clubs or wherever.
Anyway yeah, sorry if that comes across as preachy, I can understand where you're coming from, but it's definately fun even without drugs, at least for me. My first true 'rave' I was sober, and I had fun just dancing/socializing/laughing at all the munted people roaming around.
A sober night every now and then helps you keep in focus what it's all about and not get too caught up in getting fucked up on drugs, it's still fun, in a different way perhaps, but I find I enjoy the sober nights as much as the high ones.
