Of course everything is ultimately made by non-hybrids. All Uniques are Superhybrids. All Superhybrids are made by combining a non-hybrid with a hybrid and all hybrids are made with 2 non-hybrids. It takes 3 non-hybrids to make a Superhybrids.
To make the Erlidominus for example it is going to take non-hybrid DNA from a level 20 Erlikosaurus (200 per fuse), a level 15 Tyrannosaurus Rex (50 per fuse) and a level 15 Velociraptor (500 per fuse). To get these dinosaurs to level costs 3,150 for Erlikosaurus, 850 for Trex, and 11,300 for the velociraptor. Then once you can start to create and level Indominus it is going to take 900 DNA to get it to level 20 so you can use its DNA for the Indoraptor creation. Based on the average of 20 per fuse it is going to take 45 fuses to create and get that Indominus to level 20. That’s an additional 22,500 velociraptor DNA and 2,250 Trex DNA that will be needed. Now it’s going to take 250 Indoraptor DNA to be able to create it. That’s about 12.5 fuses so let’s just say 12. So now you need an additional 2,400 Erlikosaurus DNA and 600 Indominus DNA which you will have to create and will take about 30 fuses. That’s another 15,000 Velociraptor DNA and 1,500 Trex DNA.
For Indoraptor it will take about;
48,800 Velociraptor DNA (Common)
4,600 Tyrannosaurus Rex DNA (Epic)
5,550 Erlikosaurus DNA (Epic)
Of course if your lucky with fusions and with Ludia giving us the opportunity to dart hybrids sometimes these DNA costs will decrease.
With close to 20 Uniques that is a lot of DNA to have to obtain. Giving players a special currency as a reward for certain events to select any non-hybrid DNA they want is not going to cause a massive flood of Uniques being created overnight. Especially if the exchange is scaled to the rarity of the DNA so 100 of the special currency could be used to purchase 100 Epic DNA, or 400 Rare DNA or 900 Common DNA. There are no Legendary or Unique non-hybrids so those DNA’s would not be exchangeable.
Edited to add: even if they were to give 100 special currency a day for completing the daily mission reward it would take nearly 5 months to collect all the DNA necessary to create an Indoraptor if the player was starting with 0 on any of the needed dinos.
Would also like to add that you could also only exchange for DNA of dinos that you already discovered and created. The system couldn’t be used to fill in those dinosaurs are missing from your collection (you would still have to go out and find them).
