So far, I like the new feature! I've played around with it a little and got some L orbs and joker orbs among other rewards, I loved that! Food is welcome, too, I'm notoriously short of it! And I'm looking forward to get the Mastery dragon. The gold rewards are way too small imho. And I don't care much for trade essences, I've got plenty of them. Dragon Rescue keys as reward would be great!
I think that SP heard our complaints about useless breeds/hatches for events and this might be their answer: Some sugar to ease the pain of having to bred/hatch hundreds of Terra dragons for some event.
Compared to the features "Goals" and "Dragon Collections", I like the new Mastery feature best. Some tasks are easy to accomplish, you can do them "on the way" to some other task that you're trying to do.
I like it too that the new feature has hatching tasks, not breeding. It may be easier to hatch an existing egg from storage to achieve a Mastery goal than to try and breed it (this is too erratic since Breeding Reborn because previously straightforward breeds like Flame and Electric may yield unexpected and unwanted results now). On the other hand, this puts additional pressure on hatching. My hatchery is working at full capacity all of the time anyway! It would be very welcome to get more hatchery slots.
About master points... Active players and wallet warriors will benefit from it. Good for SP, but also good for us? I'm not sure yet.
And I wonder if every player gets the same goals? Hatching an epic or legendary dragon will be far more difficult (maybe impossible) for a low-level player, but it's no sweat at all for me (currently level 101).
I also wonder if the rarity requirement might be changed to "at least" rarity - i.e. if I hatch an epic egg it counts for a mastery task which requires a VR egg?
Ready player one?
...oh, and I'm female. And a fighter, not a collector! 😂
