Losing team gets no drop, fixes people joining war only for items and not trying and all get free items. Just stop the losing team from getting any rewards, instantly everyone is a try hard.
You keep making threads and no one keeps caring about them. This idea has been suggested many times before you, go add support to one of those posts.
Are you stupid? Not everyone wars just for items, on the losing team at LEAST 6-7 people are active wanting the win so if they don't get the win they get no items? Great idea, not. Think before you speak/type.
