I did some research and there aren't many people with HP to delegate, so I focused on the top 20. I totally agree with giving people a boost to increase their HP; I think that's good for everyone, but I think I'll start with a lower cap (500 HP) with a maximum possible total of 5 points per day (1 point for every 100 HP).

Another point, I don't think it's a good idea to start the mission now in the middle of the season. I was planning to implement it now, but I think that wouldn't be good, so I thought about enabling this mission at the beginning of season 3 or scheduling it for next Sunday, the 18th, so everyone has time to prepare.
