...Using mithril to go around a limitation that should exist is obviously an issue. If barbarians were ALLOWED to wear full plate, they wouldn't have bothered to write all that verbage about them losing abilities if they wear heavier armor. It negates a balancing factor, therefore, it IS a balance issue.
When everyone in the party is wearing mithril, you know it's cheese...
Disagree. With that reasoning, things like Power Attack and Natural Spell are cheese (no 2HF or druid should leave home without them). That Cure Light Wounds wand is cheese, because every sane party wants one (unless they can get Lesser Vigor). The Divine Power spell is cheese because every sane battle cleric memorizes it.
3.5 presents a lot of meainingless choices and gives players a ton of useless, suboptimal options to wade through (like the Acrobatic feat). Just because some options are better choices than others don't make them cheese.
Note that the barbarian IS making a tradeoff here for Mithral full plate. First off, its freakin' expensive. If you use the wealth-by-level guidelines, that's money that can't be used elsewhere, which is a significant asset. Second, it precludes using other materials. Adamantite for DR is great. Finally, it precludes wearing a light armor for optimal mobility.
Also, ironically, your ruling would ENCOURAGE what you would probably consider to be "cheese" from players. Any barbarian faced with that sort of ruling would just multiclass or "dip" into something with heavy armor proficiency -- a fighter level or two isn't so bad, and there are tons of PrCs out there, or even cleric levels for an improved Will save.
Finally, I guess if you think its necessary to nerf bards, barbarians, or rangers, so be it... Barbarians are a strong core class, but only due to rage, really (how many Barb 20 builds do you see on the optimization forums?), and is often multiclassed. Bards and Rangers are both usually considered to be fairly weak in an optimization sense. Throwing them a small bone (a few steps of AC for a TON of gold) is only going to help them catch up.
