With so many great dinosaurs it would be advantageous for the developers to allow a 12 dinosaur team. After all, this would have players spending more of their coins building up additional dinosaurs. In return giving us the players the pleasure of having more variety for our teams. We would spend more coins and money developing the 12 dinosaurs which gives the game owners more money and happier players. Having only 8 dinosaurs I understand makes it challenging but also it limits our desire to build each and every legendary because we only can use so many.
Another option is to pick 3 dinosaurs from the 8 choice team of dinosaurs and then one from the “bench” which would be another 4 dinosaur tier of our choosing.
One last thought is maybe add two team spots for each arena a person advances to. Starting with 4 team spots for the first arena, 6 the next, 8, then 10 dinosaurs to choose from when you are in the 4th arena. Making it more rewarding and exciting as we advance arenas or possibly levels.
Just some thoughts. I know I personally would love to have more variety in battles picking from the plethora of dinosaurs. Thanks for the game.
