First of all, I think the bonus of all villages in war are too small. Each TWO DAYS I can make two attacks in a full (and hard) TH7 worthing 200.000 each one, waht is almost nothing. I can easily find a good match with over 300.000 of both gold and elixir and got to steel everything spending less than 3 min and some barbarians plus goblins. I think a good TH7 should count more than 400.000 in resources.
Second thing I'd like to change is the timing of the wars. Should have two types of war: the ordinary one and a lighting and fast one. The second one would be like this: one hour of preparation and one hour to fight. Obviously it should happen only once a week and have high resources/gens rewards (with just one fight).
