ok thats cool, saw your poll and i voted on making new typings like namakien, saiyan, earthling and such. might even spit a few typings at you for idea purposes.
The main problem with some types, for example saiyan or namekian, are the attacks. A saiyan attack doesn't have too much sense... for that reason for now I proposed the chart you've seen, mostly new types with some old ones to balance things... We'll see what happens!
