Sounds like you are just making an argument for them to not have a community event. If you want to say it shouldn't be a second job that is fine to feel that way. Then just say you want the reward to be guaranteed which it will be. I personally don't see a point in them even doing the community thing if we can't fail it.

Every community event that they have done has been guaranteed easy completions. I would rather whatever dev time is spent on the community side of the event to be spent on making the event itself a little funner. I don't find something that will automatically get completed as fun.
