(FWIW) The L2 bus is now RMB24. Usually it's pretty good but last weekend took well over 90 minutes in a hot bus withouth aircon or airflow (there was no opportunity to get up to alert the driver, who had his wondow open). The traffic was backed up all the way to the Lupu bridge. (No accidents of anything, just slow.)

For travel to Jing An I'm now a convert to the bus (mainly because of the potential hassle for a taxi at the maglev terminus).

For the return it's now either a car the whole way, or combo of taxi + maglev (I too have become pretty efficient with the transfer, and while it might not save that much time, it feels quicker and is a bit more fun )
