Refreshing Odin only disguises this concern. I'm sorry but this just seems to be a fundemental difference in how we believe Clans should work.
I agree that doing more work should net more rewards but having Odin's health refresh after every battle removes strategy and team work from the equation. What's the point of making this a team effort if your contributions only add to an arbitrary point total.
Leaving an Odin in the red allows you to use different teams, requires different strategies and gives some of the "lower power" members of a clan a way to contribute plus doesn't leave the clans full of players like this with a sense of hopelessness. Why on earth would they want to battle an Odin that they can't kill?
Edit for additional thought: Removing the need to kill Odin, also removes the reward of killing Odin. If you can't kill Odin in one go there should be some sort of punishment. Just refreshing Odin removes that punishment. There's a reason Odins 1-9 aren't permanently dead once you move to the next level. If you want to get more rewards and raid points for your SoB and Odin X is in the red, you can get more rewards taking down a fresh nine instead of finishing off the X.
