I like the way you can fight trainers and it gives me more to do in pixelmon other than just catching and hunting shinies and legendaries. So after defeating the first pokemon in a trainers party it skips the other ones and still gives me exp for my pokemon. its the same with gym battles. It doesnt make gym or trainer battles fun cuz you know you're gonna win even if their level is equal to yours after defeating the first one in their party.
