Sedy can you please fix the enhancement cards? As is, there are a total waste of tears, they get used up even if the enhance is successful, I bought four, started enhancing, and they were gone by the time I needed them. total waste of tears and cards

Even in money-hungry retail the protection cards lasted until they were needed, and there's nothing stating they get used regardless. Weapon cards are too expensive to just waste with these cards that don't work lol and it's way too expensive to just throw tears away buying enough cards that MAYBE will protect but are wasted even if they don't.. Can you please tweak this system or something?
