Improve disenchanting of cards of higher stars

The current season and prestige rewards in general gave us access to a vast amount of different cards of different star level. Sadly even a card of 3 stars doesn't differ from a 0 star card, once you get your hold on a four star card. While in my opinion the difference for 0 to 5 stars are to small for the amount of work and resources it takes to upgrade them, i'd love to see at least an increase for disenchanting already upgraded cards. My suggestion: increase the amount of disenchants of compendium card by the total amount of disenchants of the old card (or increase the amount by star level +1) and increase the amount of essences gained from disenchanting an upgraded card
