I don't know. If I'm honest, the only reason I get any enjoyment out of Pantheon is to see how high of a rank I can get. The randomness of maps and game modes is highly unenjoyable to me in general (2v2 or 3v3's on 5v5 maps, making for very long games).
If I'm just gonna goof off and have fun or play with randoms, I join customs.
Pantheon just has too many issues for me at the moment.
*edit to add
I have not played in the most recent Pantheon, aside from one game to test out the new changes. So my above opinion, is simply that, and is not based on any up to the minute changes.
