I figured that would be the case, but I would still be down. If anything we could ban some Ubers? Some Ubers will definitely fit in though. We could get some epic Type: Null/Slivally vs Arceus battlesMaking Tier Shift ubers based was discussed before it was submitted this gen. Overall the consensus was that the power difference would still be too great between Uber pokemon and lower pokemon and besides what's the benefit from including ubers?
Also lost heros, Ubers would add more variety to the Tier Shift scene. Regardless I don't think the 'power difference' between Ubers and the others should even matter much. Taking some Ubers down with maybe a PU mon sounds very rewarding lol
