I like having one armor per AC bonus, or thereabouts. It means armor proficiency can be easily balanced. Plus, why would would wizards (controllers) wear heavier armor than rogues (strikers)?
I believe they've gotten rid of bucklers and tower shields (I could be mistaken) so that'd be a step in the right direction.
Sorry, I didn't mean controllers, obviously. What I mean is heavy, medium, light, none categories to fit the front line, support, ranged and casters categories.
Generally, people get the best armor they are allowed to/can afford to get. You won't see many fighters past their first adventure failing to don plate the second they get back to the big city (unless they are two weapon fighters or the like in which case they'll take whatever the best armor they can get and not compromise their attacks).
Having a different armor per AC is excessive because people don't tailor to a particular AC; imagine having a player say, I could be at AC 12, but I'm going to stick with these furs and shield instead, even though it keeps me at AC 6. Yeah, people dedicated to keeping their player fully in character no matter the cost might do this, but that's a relatively small portion of players (well, that I've ever played with).
Also, with ACs able to go to whatever they like now, it's clearly not practical to have one per AC anymore. Granted back in the 1e days there were 9 or so achievable ACs from non-magical means and they filled out the wheel and had a different armor combo for basically all of them. How many people used Padded, Studded Leather, Ring or Splint mail, though? Magic-Users wore nothing, Thieves wore Leather, and everyone else wore Plate as soon as they could. So, in effect there were two armors that people chose to wear (unless you houseruled chain onto some classes, etc.). 2e basically didn't change this at all but added Full Plate, which those who could started wearing. I can't speak for 3/3.5 with any expertise, so I won't.
Though there could be a very large number of different armors, the reality is there are only about 3-4 types that people use. I say, better to have the system support the reality than fill the wheel.
