People are actually surprised Arceus won? Most people don't play for the official competitions and the like. Alot of people can't get to a place for a distribution event. So it's a no brainer most people would chose something like Arceus. And considering everyone knows Arceus has the highest stats and is viewed by many as the god of the Pokemon universe it's no surprise it won.
Hey, I wouldn't had minded the Ditto, I voted for Arceus first because it would give me a few laughs through my next playthrough. But then I realized Ditto's true value. I wanted Ditto to win. But I'm not one bit annoyed or ticked that Arceus won. Because frankly it makes sense and it's actually a fair choice for people.
Arceus, but I would've been fine with Imposter Ditto.
I guess I didn't care who won as long as it wasn't Mudkip or Palkia. (The latter didn't even come close, lol.)
The problem I'll be facing, however, is that to me, level 100s are too awesome to use outside of Wi-Fi and PBR, and in the former, I'd ban Arceus anyways because I still think global base-120 stats and Multitype render it completely broken. ¯\o_O/¯
...Why did everyone want Ditto, anyway?
Arceus is a good choice, since there are probably a lot of people (myself included) who missed getting it the first time around. I still had my hopes up for Deoxys, though. Or Jirachi. I never did distribution events back in Gen. III, so I missed out on both of those legendaries.
Hopefully Imposter Ditto gets released in the future. It will really be a neww type of troll in competitive battling.
Ditto would only be able to make more Imposter Dittos, and as it can't make more Dittos in the first place, it'd be useless in breeding.
