Absolutely fair. Only three and a half years ago I was trying to beat my friend's expanded Mad Party/Zoroark GX deck with a Vikavolt V/Malamar VMAX/Honckkrow GX deck that I loosely based on a 2016 Expanded Giratina EX/Seismitoad EX deck from an article on Pokémon's official website, and now I have friends who are starting to buy World Championship reprint decks or build their own Chien-Pao ex deck from the ground up. I've spent such a long time researching competitive Pokémon from throughout the game's history that I forgot what it was like to be a player three and a half years ago, but watching these dear friends who I met for reasons completely unrelated to my hobby dipping their toes into the game and trying to build the best deck they can from scratch, or buying the best deck on the shelves without caring how up-to-date they are or what tier they are in, has reminded me of that experience.I don't really care about what's playable and at which rates in Tier 1, because that concerns a minuscule amount of players. There are going to be great decks and perhaps even dominant decks. We also aren't nearing some kind of "true balance", arguably the entire "multiprize" mechanic is innately unbalanced, but we have to celebrate baby steps when we get them.
What I care about is the grand majority of players who don't netdeck, most of them not even playing the game outside of their living rooms, having a welcoming environment where they can pop to their local game store, whip out whatever random deck they've got and have a fun time where they don't go 0/6 0/6 0/6 because there's a certain class of cards that is just miles ahead of a regular card.
P.S. What percentage of the "grand majority of players who don't netback" would you say buy something like a League Battle Deck or a World Championship Reprint Deck? One of my friends saw Tord's Gardevoir ex deck on YouTube, and another had an older brother with competitive Pokémon Video Game Cup experience who bought a Worlds reprint deck after researching them and a younger brother who copied the older brother. I'm working from a fairly small sample size, so I'm wondering how common this is. (I'm probably crazy for describing someone who grabs a pre-built deck off the shelf as "not a net-decker," but it's not quite the same as scouring tournament results and copying a deck that won LAIC, the Barcelona Special, or Wisconsin Regions and trying to grind League Cups with it.)
