Because @Nestea (and possibly others) demanded it.
This is the inaugural tournament for Indominus rex Gen 2. It is a three day tournament. Almost exactly a year ago, we had a tournament for the original Indominus rex. It was a three day, four hour tournament and requires 1354 trophies.
I rex Gen 2 is a much newer and shinier hybrid. Hybrid tournaments tend to run higher. First-run tournaments tend to run higher. It’s not a tournament hybrid and most players that can reasonably expect a Dominator finish probably unlocked the component creatures a couple of weeks ago, so I’m not sure how much of a bump it will get. On the other hand, Indoraptor Gen 2 is now almost certainly coming soon. More copies of the I rex will be needed.
Until we know more, I would look hard at that 1354 from last year. Stay tuned for more.
