I honestly don't care either way. That wasn't meant to be offensive, but it's true. But there is one thing. I recently found out the only reason we accept Solar System Cell is to get people to shut up (found that out from Azzy himself). Catering to DB fanboys is not cool, and we appease them enough as it is. On the flip side, if we got used to it once, we can get used to it again. Not to mention that the character would simply get stomped by all 2-Cs except for Zeno (ironically), SB Janemba (through "canon") and the Three Golden Goddesses (due to speed. get's stomped otherwise), and would simply just be there as a figurehead, for lack of a better word. And I'd love to close Goku vs Arceus/Hades/Lucemon/White Face matches. On the other, other hand, we'd be going on a slippery slope, and I'm certain myself as I was about to ask for a composite Superman profile for fairness if this goes through, but stopped myself. And unlike other composited characters, like Link, some Pokemon, or a good portion of Digimon, he's the exact same character throughout all continuities, going through classic Dragon Ball, Dragon Ball Z, and some of Dragon Ball Super with minor events changed. We've deleted a handful of profiles that were just one different Goku (see the deleted Goku XV page that simply had him at 3-A when we had him at 3-B+).
All in all, DB fans shouldn't be unhappy with us, and I could easily go both ways with this. I understand both points. It'll do no real harm, being one of over ten thousand, but it'll make us look like we caved in to fanboyism. I'd give this more thought, but I currently have a more important task at hand that'll probably keep me up all night. Sorry if I bothered anyone.
Also, I don't know what his tier would be. SB Janemba is a potential glass cannon. He's be at least Low 2-C (Goku, I mean), due to XV.
