I also wish there was a place to submit ideas we'd like to possibly see in Gen V without doing something like CAP. If it isn't against the rules, I'd immediately start such a thread.
One thing I'd like to say about normal is that it is almost never paired with other types. Besides flying, Girafraig, and Bibarel, both of which are NU, Normal is always on its own, so I'd like to see some more creative pairings with that type. Plus, Normal+Fighting+Scrappy=Unresisted STAB, and Normal-Ghost = IMMUNITY, not resistance, to the otherwise unresisted combination of Fighting and Ghost.
