You have a plethora of pokemon that evolve at a "standard" rate, relative to the games introduced before it, and then you have outliers like Mandibuzz, Braviary, and Bisharp that aren't accessible until level 54. It doesn't hurt to mention that these pokemon aren't particularly impressive compared to others you can get much earlier, so it doesn't feel like an impressive reward in the same way Dragonite or Garchomp feel like grind rewards.
If you're playing blind, there's little chance that you would keep these late bloomers in your party by the time you get to the E4 when you have fully evolved options available. In my experience, any first stage that reaches 50 without evolving I fairly assume to be something that trades via some obscure item or method that I haven't found yet, so I bench it for something that pulls its weight.
If it were designed properly, then you'd be fighting enemies that also are high level but aren't evolved either, at least once in a while. But any important battle you starting at about the 6th gym in BW won't have anything but fully evolved enemies. What good is Rufflet now?
