If your clan scores max stars (e.g. score 105 stars in 35v35 etc) in a clan war u get an extra % of war loot (say 50% etc, although tweak it down if 50% is too much).
Please comment below or add your own suggestions, as this is just an idea.
EDIT: This is assuming you won the war (as the other clan could get max stars too, and therefore a draw).
