As of now the Alphas have no point other than an experience boost IF you can manage to kill them. They are far too numerous and OP. They need to either be removed completely, or made SUPER rare and nerf them hard. As it is it makes it very hard to get a start with OP alpha animals showing up and chewing up your tames and buildings as soon as you get them. And making a tame nerf on top of that will make things even harder.
I want to like this game, but I'm having a hard time of it.
