The reason why EDs aren't as common as mimic ian is because EDs have different breeding cycles and it happens to be slow, and we know that Rathians and Rathalos make babies every year hence the los would want to mate with a strong ian and who is the strongest in your opinion...Rathian Sub ( to me it's still mimic ian)!
