Right now, any champions that can be upgraded with the combination of champion fragments and wild fragments will light up. This has made the "Upgradeable" highlight so beyond redundant. The appeal of the highlight being only for when you have enough champion fragments is that champion fragments are passive, one-purpose currencies that you often would have too much of a variety to perfectly keep track of. This was supported further by the fragment progress bar as well, but the champion fragment bar is now only visible on any 0 star champion, the moment you get a deck to 1 star that bar just disappears. The "wallet" is also about as useful as a wallet full of unsorted coins in real life, if not less, because you have to go back and forth to check if a certain champion have enough to be upgraded. It's as if you now have to use that bag of unsorted coins for a vending machine that has a slot for each coin type.
Changes are necessary because they are adding a lot of new currencies beyond just fragments, but this was definitely not targeted for people at my stage of the game where you're mostly still grinding champion fragments and wild fragments and haven't 3 starred everything.
