Means you either suck at darting TRex or have been asleep the whole of June. Ludia practically poured TRex DNA for us to dart.
If you are saying less likely due to options aka IndoR isnt worth spending TRex DNA on, then i agree. My IndoR was lvl 29 when I stopped lvling it in favour of Tryko (lvl 23) and Erlid (0/250 or lvl unmade). Now both are close to lvl 30. Same time my Draco went from lvl 17 to lvl 30 with a huge spending of scents and being in the correct local.
Also Draco needs 12k DNA. IndoR need 3750 DNA. To be level 30. About 3 times plus difference.
IndoR is my first unique. Made in a time when VRaptor was quite rare. It was worth making then and was lvl 29 along with my SteGod when 1.5 dropped. So about 5 to 6 months to go from zero to lvl 29. No knowledge of hunting, no skill in hunting to being able to hit 300s on most commons.
To me, IndoR is easy to get and lvl but got less worth doing so.
The easiest legendary i think would be SteGod then the 2 Sino hybrids. Draco is 4th.
This is based on someone playing since Feb and not starting today. Now with scenting and proximity to Local 2 and 3, Draco might be easier. Even then you need to have a job that allows you to play for hours in the day.
