No, people would still pick those Pokemon lol. It'd be Pokemon that no one remembers like at all, such as I dunno Claydol?I would love to see what people can think up for Lapras, but I'm probably not random number generator. Keyword is "Probably". XD
I can see why the number generator is used. If we chose the Pokemon, then all the good Pokemon would be done at from the start, and nearing the end of the generation, all that would be left would be the BU and NU Pokemon along with most of the UU Pokemon. It wouldn't be fun at all.
