Why do people want progressive items but not specs?

There’s literally a sticky post declaring their intention to update certain items over time

To anyone asking to justify why something should progress the way classic originally did:

The burden of justification has always been on the changes side of things. Talents effect everything a player does on a fundamental level from how you level up to how much dps you do.

The best argument I could see for progressive items but not talents is that talents don’t invalidate or cause you to skip content. They just augment what you can do with what is already in the world.

Something being inconvenient like resetting your talents all the time hasn’t been a good justification for something to not be in the game. Such as mail taking an hour
