Bare minimum here also.
I can usually fill my daily mission battles/incubators with the strike towers. Some days it means holding off on a multi-step tower until the next day if my battle count is already met.
I do enough to get my daily battle incubator, for Alliance missions, then I am out of the general arena.
I do not mind the Friendly Challenges for battle count missions. I have a great Alliance where most like to use skill more than RNG or the swap in death. Put in a good team and see if you can out play your opponent. We do have a few that like to mix it up with all evasive strike, or all swap ins and even that is fun at times.
I used to always keep an incubator going and liked the general Arena. But for me, the meta has devolved into something that is not enjoyable anymore. The match making also leaves something to be desired. I would not mind an occasional much higher-level team, but when it becomes the norm, it gets frustrating and I stop. I do not worry about trophy count, so have no concerns about making progress or not.
I find it relieving when Rank 4 Defense is reached and I do not have to battle for the daily for a few days. I am a hunter and enjoy the search for what I need and the darting. If I did not enjoy the hunting aspect as much as I do, I would have left the game months ago. If the battle requirements were increased to where I was required to do more battling for the alliance, I would leave the alliance and go solo to just hunt. If the game itself required I do more battling, I would just stop playing.
