It really is hard to break down the Tyrant tier because there is a decent amount of balance right now.
Now if we base a tyrant tier by observation of what the Top 40 players are using, we get a decent picture.
Please note this list is based on Top 40 player usage I made on August 15th.
Top usage Tier. Thoradolosaur, Trykosaurus, Dracoceratops, Diorajasaur.
There is a clear separation between these 4 and the rest of the pack in usage. Of note, Thor can usually beat the other three in this tier.
Middle usage Tier. Erlikospyx Dilo, MagnaPyritor, Erlidominus, Utarinex.
Of note: Teams that used to carry Erlidominus have been migrating over to Erlikospyx. Only 20% of the teams carry both Erlidominus and Erlikospx and 50% of those said 20% teams don’t carry Dilo. So I think it is safe to say that Erlikospyx is climbing up to the Top tier and replacing other dinosaurs, while Erlidominus is dropping.
Bottom usage Tier Tenontorex, Monostegotops, Geminititan.
So Geminititan has a use rate of just once, but it was by the best team at the time I did this survey. The components to make this dinosaur are very hard to get and clearly lots of hard work was involved in getting this creature to combat worthy level. Also when it first came out, it was barely passable, so it did not have a good investment rate among players.
Monostegotops does well in match ups but seems to be dropping off of teams.
Tenontorex is a guessing game dinosaur, where the correct choice can give you victory.
Other notes. Tenontorex is capable of beating all 4 of the top tier on this use list as well as Erlikospx.
Other stats: Only one team carried Monosteg and Tenontorex at the same time.
Teams that carry Monosteg, only carry Diorajsaur 33% of the time…
Teams that carry Tenontorex only carry Diorajsaur 58% of the time.
Two dinosaurs not considered Tyrants are Quetzorion and Grypolyth… Considering the usage rate of 40% among Top 10 player rosters, this status might need to be revisited, especially for Quetzorion.
Of note: Quetzorion has park only components, besides the Tanycolagreus component which shows up every Thursday. In theory, with good shooting,a player could open about 60 to 100 epic scents in park areas at night and walk briskly around, and have a good chance of getting the rare and epic components needed for this creature to get to level 29 or 30. Of course that requires a stiff time commitment, a thick wallet, and a safe park to walk around at night with a bunch of supply depots in range.
Two other outliers of note for possible future discussion would be
Ardentismaxima and Procerathominus.
