Clan XP Points : Encourage players to make attacks when the war is already lost/won

The changes I propose are thought to encourage players to make their attacks and give them a goal even if the war is already lost/won. It's so frustrating to have trained 10 dragons and now they're just useless...

1) For now you get the same number of Clan XP Points for any succesfull attack.
In my opinion, there could be :
1 Clan XP Point bonus for a 2 star attack
2 Clan XP Point bonus for a 3 star attack

2) For now you get : 10 Clan XP bonus for Scoring 40% of Possible stars and 25 Clan XP bonus for Scoring 60% of Possible stars. These bonuses are so easy to reach !

In my opinion, this should be :
5 Clan XP bonus for Scoring 60% of Possible stars
10 Clan XP bonus for Scoring 70% of Possible stars
15 Clan XP bonus for Scoring 80% of Possible stars
20 Clan XP bonus for Scoring 90% of Possible stars
25 Clan XP bonus for Scoring 100% of Possible stars

3) Reduce the victory bonus down to 25 Clan XP Points (instead of 50), because you already have the Ressource bonuses.
