Choreographers

This topic is related to the choreographers of JDJ.

My question is that when each and every year new celebrity contestant participate than why not new choreographers?? I mean, Choreographers who won the title in the previous seasons are again participating.

Is this fair?

And what about those choreographers who are participating from last few seasons. It's like every season along with few new I see some old faces trying to teach dance to the contestants and if this continues there would a season when all the choreographers will standing with their JDJ trophy after participating in god knows how many seasons. (Some may even be standing with more then one if winners are allowed to participate again)

If you are bringing in new celebrity than you should also bring new choreographers.

What's your views??
