Different people have fun in different ways. If I can take a feat that lets my wizard wear heavy armor in a meaningful way, then that changes everything about how looks and acts and perceives himself, even if the only mechanical benefit is having a high AC.
I thought the fun of feats was that they let you customize your character in interesting ways, not necessarily that they add great complexity or make the character more difficult to play. I'm already juggling enough actions on a round-by-round basis.
Please don't misunderstand me. I'm not judging how different people use or find enjoyment in the game. I'm simply providing my perspective on what I find fun and my table experience. And from that, passive or purely mechanical abilities have provided less fun or enjoyment than abilities that are more active and flashy. That's not to say passive abilities can't be or aren't fun, but in general that is my preference.
But I also think as they are currently designed, a 2-3 feat tax for a wizard to get heavy armor proficiency is way too high. But also, I think armor feats would fair better among other options if they granted proficiency in addition to adding something new, as most feats do (especially the more popular feats).
