Hasn't the TCG had a problem with encouraging people to use a greater diversity of cards - in this case, more than just Basics and Basic-EXes and consider using Stage 2 evo lines - for the greater part of its history? My understand is that Haymaker and Haymaker-like decks defined the meta in the early days, and DP had a bias towards Lv. X cards that evolved from Basics, and then Pokémon-SP were pretty much a concession towards the meta (despite the existence of Broken Space-Time) in the Platinum era.
BW's when I stopped paying attention, but it sounds like Basic EXs started taking off, but they never even tried to introduce Stage 1/Stage 2 EX cards to see if they'd survive. Again, a concession like SP. I know BREAK cards exist but I'd be surprised if they've done very well, effectively being a Stage 3 card in some cases.
As has been said, I'm more of an anomaly - most collectors are gonna *like* the embossed shiny Pidgeot-EX - but I know when I pulled one, I was a bit bummed out that it didn't evolve from Pidgeotto, and if I could trade it for a Ruby/Sapphire era ex, I likely would.
