On descent into CLT; open descent; 6;000 selected in the altitude window. Approaching AAIRE on the JONZE 2; I asked the FO to verify our descent clearance as it didn't feel right being cleared to 6;000 with departures at CLT coming off of 18C. As I asked this; I disconnected the autopilot and arrested the descent at 8;820. The frequency was quite congested (CLT Approach) so the FO was unable to get a word in. However; as I continued the climb from 8;820 to 9;000; CLT Approach did ask us to climb and maintain 9;000. To my knowledge; there were no traffic conflicts; however it was a very uncomfortable situation.Flying into CLT has become problematic with the CDA arrivals. The CHESLY has become legendary for altitude busts; and the JONZE 2 isn't much better. The scenario goes something like this; you check in with Atlanta Center and receive a 'descend via' clearance. Not long after; you are turned off of the arrival and given a 'descend to and maintain' clearance. This process usually repeats itself a couple of times (either with Atlanta Center or Charlotte Approach) before you are assigned a final descent clearance. This system makes it very difficult to fly the arrival. Please know that this isn't pointing blame; but pointing out a problem. As PIC; the responsibility ultimately falls on me. However; a smoother process would be helpful.Eliminate the CDA arrivals into CLT. We rarely fly them as published.
Air carrier Captain reported an altitude deviation during approach to CLT while on the JONZE 2 RNAV Arrival.  Captain stated the CDA arrivals to CLT are allegedly problematic and should be eliminated or a 'smoother process' should be implemented.
