While the new design is a bit more visually appealing, it's less functional overall.
1. Favourite icon is significantly more difficult to distinguish between on/off.
2. When an ability is maxed, it dims the second line which also contains the Basic, Special, Unique, Leader tag, which is arguably more important than the name of the ability itself. I'd take a cue from ships and move the ability level into the icon's lower corner, so it's either a #, an omega, a zeta, or a checkmark (for maxed non-zeta/omega abilities). Then brighten up the ability type tag so it's as visible as the name.
3. No Find button is bad. Remove the mini-potrait beside the stars and replace with find.
4. Jumping to the mod screen seems to have a mod initially selected, showing its stats instead of the heroes stats and the Loadout button. I'm guessing this is a bug and not intended.
5. Mod loadout on main screen is small enough on a phone that it's very difficult to distinguish certain set types, especially if it's purple.
6. Use of space on a rectangular phone is pretty bad. Lots of empty space with tons of stuff crammed at the edges. Relic and ship button seem like they could fit nicely under each set of 3 gear slots. Instead the relic causes most Legendary and HJ heroes' abilities to scroll.
Seems like they dropped the ball on UX pretty badly in this redesign.
