Allowing wizards to wear armour is quite possibly the worst 4E idea so far and the one most likely to kill D&D. There are two reasons for this:
1. D&D depends on iconic fantasy which itself draws on a shared aesthetic. The definition of "iconic fantasy" is being discussed in another thread so I won't dwell on it here except to say that more people are familiar with the image of a wizard in robes than one in full plate, and the game should encourage familiar images because generally that's what people like.
There used to be an RPG called Talislanta that sought to completely redefine fantasy. There was nothing mechanically wrong with the game but very few people play it nowadays. Why? Because people like that with which they're familiar. Attempts by game designers to redefine fantasy are pretty much doomed to fail.
2. D&D has always relied on mutual dependence between characters to maintain party unity and hence the co-operative nature of the game. For this reason, each class had its own strengths and weaknesses. When you blur the class roles, you undermine the glue that binds parties together. Mix class roles enough and you get each character as a largely self-sufficient 'vanilla' superman without the need for anyone else. The game shouldn't promote that way of thinking unless WotC are hoping to turn D&D into a game of one DM and one player.
Hmmmm, maybe.
But I think, aside from all that, the real main reason for it is that they don't need the restriction to balance the classes anymore.
In previous editions, mages were the uberclass. They could do anything. A spell for every need. Played well, the mage is the destroyer of enemies, divinier of riddles, opener of portals, gateway to the planes, and solver of every problem.
To balance that out, he's imminently killable. Very low HP and very low AC means that he needs a party to protect him. Combine that wil few limited uses of his magic, and he really needs a party of protectors.
Let's face it, if wizards in 3.5e got the HP and BAB and armor/weapon selection of, say, a cleric, who would play any other class? Or more specifically, which powergamers would play any other class? And, even for those of us who roleplay our characters and pick classes based on what would be fun to play, wouldn't we all feel really worthless compared to the armored, fighting, spellslinging mage with the AC, BAB, and HP to take on all challenges and the spells to make him a demigod?
Now, with 4e, all the other classes are gaining uses of abilities that enable them to do some of the things mages used to. And mages are losing some of their versatility.
Since the classes are becoming more balanced, and since the mage is no longer the solution to all problems, there is now no need to balance them by making them so killable.
So why not remove a restriction from them that was originally just a game mechanic to try to balance them, especially since they're much more balancexd now without it.
