We all have our favorite type combos, both favorites that are exist, and favorites that you want to see happen. But for a different direction, what are three type combos you really don't want to see, be it cause we already have enough and your tired of it, or you just don't want to see them create this type combo.
Top of my list is Normal/Flying. Its been done so many times, and really it just ends up feeling lazy in the end. I'm hopeful that with Fletching->Talonflame that at least any we do get will end up something a bit more creative. Also pure Water, and Water/Flying, the later partially cause of x4 electric weakness, but both cause, they come off almost as uninspired as Normal/Flying. Its near water, must be Water type. Near water and has flies, Water/Flying.
