No, it doesn't change the gaming experience. It changes the look of the game a bit, just a bit, but the gameplay stays all the same.
A price of two bucks, maybe even three or four would've been justified if we had gotten four new Raptors instead of four cosmetic skins. Like that each Raptor from the Squad has its own stats and rating that differs them from the regular Velociraptor.
Oh, and don't come with "fRoNtiEr HaS tO pAy iTs eMplOyEeS", they seemingly didn't have a problem with releasing an entirely new dinosaur, the Nasuceratops, with skins included for free. They just knew the entire community was waiting for Blue and the other three Raptors, that's why they charged money for the pack. Supply and demand, when demand's high, prices will go up. And just because there are other skins or packs that are even more expensive that doesn't make this any better.
