Evolution Candy Cost
Im looking at the costs of evolution for pokemon, and the trend for evolving twice is the second evolution costs 4x as much candy as the first one, which would put pokemon like togetic to togekiss and Rhydon to rhyperior at 200 candy (as togepi to togetic and rhyhorn to rhydon are 50 each) and its projected in the best of evolutions guide to take 50 to get togekiss (which is the same candy cost of evolving togepi) and 100 to get rhyperior.
Does it seem like they'd drop the cost of candy down, or will this be a break in the trend of second stage evolutions being 4x as much candy? (keeping in mind no pokemon take 200 candy to evolve, it is either 12, 25, 50, 100 or 400, with 3 stage pokemon having 50 or 100 as the final evolution cost currently) And if they do drop the cost of candy for evolving, that would suck for people who already evolved those pokemon

Disregarding the cross-gen evos, none of the Gen 4 Pokemon in the main series have a unique method of evolution in the broad sense of Feebas having a unique method. Everything is either level up or happiness, which as seen with Crobat and the early batch of babies in Gen 2 just get the standard candy treatment. I could see something being given the 400 candy treatment but I expect anything out of the ordinary to be reserved to the cross-genners, namely evolution items and potentially needing to have a special move learned.
