Time to segregate elite level boarding?

I have been flying out of PHL on DL for a number of weeks now. In addition to the awful gates that Delta uses, especially A13, the end of week flights often have a huge number of elite level passengers. On some flights over 80% of the seats are filled with Silver, Gold or Platinum travelers. Delta seems to have dropped the zone 2/zone 3 groupings for frequent travelers concentrating everyone into zone 2. When you have between 80 and 110 (yes, that was the number announced for one of the flights) people waiting to board an MD-88, chaos ensues. Even more so when a poorly designed gate A13 is being used.
So I think, Delta, it is time to re-think your process, and return to a segregated boarding. It would either have to be all elite levels, but by row, or, as a biased high level elite, even better would be zones by elite level, i.e. Platinum zone2, Gold, 3, etc.
For flights where the number of qualified passengers is below a certain threshold, e.g. 20, the gate agent could call the three zones simultaneously.

C'mon Delta, give us really frequent travelers a break
