I like the rewards have changed,but no more hero crystals there, please bring back hero crystals to treasure mining rewards. As far as I am concerned this is the only way to get them. I hardly need them for rolling zephy ss.
Hero Vestige is available in game via some F2P events such as Pirate's Booty, Discount Store, Catch A Prize, etc.... However it is always a good thing for rewards to be updated from time to time, this also means that some of the things we might like will be added or removed.

Not all changes are welcomed but this is not something we can change. As You can see there are not many folks which can agree with You, as this is personal perception. You can always save gems, and use them when there will be Hero Collector with Zephy as reward + Treasure Mining events in same time. You can also use Hero Hirer to lower rolling cost, therefore roll more heroes and have higher chance of finding Zephy this way (like i did today).
