As previously mentioned, the real issues to me here are both the entry cost, and the rewards. I would add another point : impossible matchups.
I did only play Gyro (VIP) four times. Two times with Jurassic Creatures, one time with Aquatics, and finally once with Cenos.
Those with Jurassic were a cakewalk. In one of the final games, I beat the whole team (mainly herbivores if I recall correctly) with just my indoraptor left. Two complete successful gyrospheres, two Alangasaurus as rewards. Great, isn’t it ?
As for the Aqua and Ceno, I couldn’t make through stage two, as my top creature was inferior to the weakest one of the opposing team. And I got two Majungasaurus as rewards. Wich is great, I’ll be able to make Alangosaurus to go with the previous ones I earned. Right ?
To sum it up :
-The entry cost is way too high
-The rewards are underwhelming, and certainly do not justify the 250DB
-Team making and matchups are inconsistent and sometimes don’t let any chance for the player to win
