Overall, I think Glaceon might be a problematic Eevolve for the vast majority of players, so I hope the article is wrong on the theory that eevolving depends on the weather, or that Niantic also releases several alternative means to obtain Glaceon. Not just through a naming trick, but also through quests and raids.
Yeah they turn off the comments more and more recently. Not sure why that is…
The one im afraid of is Rhydon to Rhyperior becoming a 400 candy evolve. I got 4 candidates ready to evolve, but only 130 candys for it. If it turns out its not 100 but 400 needed, its gonna be rough.
