What game types are you playing? I've been playing every day to get the cabbage challenges and I haven't been in a lobby with a bot since the start of that event. This is across SMASH, Nemo Kart, and just regular quick play whatever they call it (the one where it's either last stand or team score).
What do you think devs and players should be doing better? You mentioned mechanics, what specifically do you prefer? I know they've nerfed a few weapons some of which should be reverted, but I don't know of any other gameplay mechanic changes. Adding SMASH and Nemo Kart was a huge W IMO.
Not sure what you expect players to do. If they don't enjoy the game, they're going to stop playing like you claim to be doing. Unless you mean the people asking for nerfs to everything. In which case that's probably part of the problem.
