Maybe. But by small amount I mean just a couple. You’d have to defeat (not just see it in battle) the dinosaur a lot to collect enough to actually unlock or level any dinosaur. Hybrid and non-hybrid dinosaurs are both viable sources of DNA. Although possible a person will face something they haven’t even started on yet, most of the dinosaurs a person faces in battle they should either already have unlocked or be working on. It would also help in those zones where people rarely or never see the dinosaurs. It gives players a way to collect towards and obtaining the dinosaurs they are facing in battle.
The battle coins were a nice addition to the battling, but the battle incubator tends to award DNA that I already have an over abundance. And if all incubator slots have not been filled then losing multiple battles (especially to opponents that don’t belong in the arena) just becomes frustrating. Although I tend to agree that participation awards is not a good thing in any competition, leisure time is valuable and not something that everybody has so repeated losing battles against players that intentionally derank themselves is an infuriating chore that many don’t want to use their limited free time with so gaining a little something for that time at least makes it not feel like quite the waste.
