I think this is a really good point. If we were still getting the fun modifiers like we did when the game first came out, then I wouldn't have such hatred for the PVP portion. Total Mayhem is actually my favorite mode. But now it just seems to be Deathmatch, 2 versions of Elimination, & Mystery Heroes (also great) all the time.
I want to play Arcade mode for fun. Move Deathmatch and Elimination modes to a comp playlist or something. Bring back the fun modes like "Healers only".

I know the custom lobby is available, but I don't want to deal with filtering through neckbeards using it as a chat room/dating service. Though I will say there are some interesting game modes hidden in the trash.
