How exactly does a clan get XP? From what I've read it is only awarded through participation in war. I don't understand the comment "The stronger target is, the more XP the Clan will receive" so does it mean if a player attacks a much weaker base they will get 0 stars or 1 stars or what? In such a case would it matter if they win with 1 star or 3? Does this mean, you get more XP for attacking a much stronger base and getting at least 1 star? I ask because this would be a good strategy provided that the war isn't close.
I'm thinking of strategies to make best use of of the 3x XP event that's coming up and want to make sure I understand how the XP system works. So far all I can think of is just make wars larger. (btw my clan sucks at war and almost always looses, due to individual player's poor attack strategy).
