I've been updating my post as I said I would, but I wanted to make a special case for this person.
CJ, from Ohio.
I've run into him three times now.
The first time, he had an 1880. He disconnected the instant he saw my team. I assume because my rank was low enough that 'he didn't want to waste his time on someone so low.'
The second time I ran into him, he still had 1880. It was a narrow match, coming down to an Ice Beam-off between Vanilluxe and Cryogonal. When it was clear Vanilluxe would KO first, he immediately vanished.
Those were both yesterday.
The third time came up today, he had 1900 points, probably because he's 'never lost a match' before. This time, I absolutely wiped the floor with him. When the match became a 3 vs. 1, he was gone.
Truly, this is among the least deserved 1900 ranks I've seen. I pity that high score and the terrible skill that it indicates.
If you see a CJ from Ohio, don't bother giving him the time of day.
