War chest - why work so hard for nothing? Either a 4* mat or min. 20 emblems should be min. reward

All players are constantly working on better teams for wars both on defense and offense. We invest most of our gems on that… Then please make us have a good reward when after several weeks struggle are opening a war chest. Like a 4* item and min, 20 emblems. If that is too much to ask for, at least one of them? Usual war loot is most often crap, War chest can provide something better.
Players are struggling and spending a lot to make the best possible for wars. And still after months work on their defense and offense teams they can open a chest giving daily coins, 10 emblems and gloves. Rewards in war chest war should reflect the longtime work putting in to that
