5 damage per day would be better than 10... remember, each Beowolf killed does 1 damage per day,  so if we have the economy to kill one per day, they almost need to number in the thousands to out DPS the players.

5 damage per day means we kill 3 Beowolves per week and half of another... and those killed Grimm do ~12 damage overall, which had we only healed Beacon during that time is about half of what we would have healed(35).

10 damage per day on the other hand means we kill 7 Beowolves per week, while those 7 grimm alone deal 0+1+2+3+4+5+6 damage= 21 total, while we could have healed Beacon with those same moves for 70 points of healing

As I hope you can see the escalation needed to account for our number of players with the latter example is huge... if we try accounting for the difference of another player who fails to show up(even for just a few days) it could mean the difference of the players winning by a landslide and brutally crushing the Grimm before Beacon even takes enough damage to matter.
