Game Ruined

I just started playing again, I hadn’t played for 3 years. I had Thoradolosaur and Indoraptor and those used to be unstoppable. Now I can have Thoradolosaur, Indoraptor, and Indominus all fight and the omegas will beat me. A level 22 Thoradolosaur or a 24 Indoraptor should be better than a level 16 omega, but Lil Eatie can’t be beat. The new Spinosaurus looking ones are also almost impossible to beat with what I have. What do I need to know and how do I beat the omegas?
