Personaly i think not very much, only two things, Better shower and water points. I went to the festival this year for the first time and the first thing i noticed when i came there(just had a 9 hour drive from Holland towards the festival) is that when i wanted to take a shower is that i had to walk a very long distance to get to the showers, and when i got there it where very sucky showers wich where hardly or not working at all sometimes. And 2 showercamps for thousands of visitors a day isn't very handy. Maybe something for next year. and 2 the waterpoints, if people wanted to get some water, they could only go to 2 points again (so far i know) where there was water, and this was arranged a bit sucky. now Don't get me wrong about this, I thought the festival kicked some major ass, but these are just 2 points wich could be improved. The rest of the festival was just incredible, had the time of my life!
