If you spend half of your overall wealth on one type of defense when many different types exist your capabilities in that field should be unsurpassed as you are a focused specialist.
A very good point and one that bears repeating. If you spend over half your entire wealth on AC, then it should be more than 30-40% effective against the same CR as your level melee brute.
30-40% is a very generous estimate. Going strictly by creature advancement rules nearly every monster type in the game gains 2 or 3 BAB per point of CR in addition to what they stand to gain from Strength, size increases, items, feats, and anything else that improves their ability to fight. The creatures with potent special abilities grow in HD and thereby grow in mundane power more slowly. However they can simply use those special abilities and attack some sort of defense that is not AC.
To block the true melee brutes even 30-40% of the time would require even more extensive fixes than those proposed by Crusader of Logic because their melee stats scale so quickly that you'd need to top out around AC 65 to qualify for this. The changes in the OP brings it a lot closer to that point, but you would still end up with AC 59 on a dedicated AC specialist who has went a great deal out of their way for the sole purpose of boosting their AC and less than this with a character who better balanced their stats.
That same character would get missed a fairly large percentage of the time by just about everything else though. It's a good start.
In the interests of comparison I present a parallel. A character who has not went out of their way at all to boost AC. They have normal full plate, a normal heavy shield, and a Dexterity of 12 for an end AC of 21. That's it. They also have a Displacement effect always active on their person. This actually is possible via Reach and Persist, however it is intended to illustrate a concept, not to be a literal example. No nitpicking the details. That's AC 21, 50% miss chance. That is the full extent of their defenses against mundane attacks. This costs well under 2,000 gold which is less than 1% of the cost to max out those defensive items. Even if you assign a gold cost to the concept illustration Displacement effect, I think we all can agree no contest it comes out to far less than 300,000.
Through the magic of reverse engineering, let's put this guy up against the same creatures the OP devised.
The first one was 'auto hitting AC 49' on a charge, which means it has a +45 to hit normally. Add 2 from the charge and you get 1d20+47 = hits AC 49 on a 2 or better. I own the MM3 and have checked. Those numbers are accurate.
The Rage Drake could Power Attack for 28 points and still hit on a 2 or better with that charge. However, half of those attacks automatically miss.
Instead of doing 17-27/17-27/10-25 it is doing 45-55/45-55/38-53. The weighted average after the single miss chance defense becomes 22.5-27.5/22.5-27.5/19-26.5. This is a bit higher as it is averaging 3 points higher on each of the two claw attacks and 5.25 points higher on the bite attack for a net result of 11.25 points more. If the bite misses though it does not get to Improved Grab so it cannot grapple and rake. Naturally this means all of the rake damage is avoided.
The AC guy goes on to get hit with both rake attacks, taking additional damage. The Displacement guy either lucks out in avoiding the bite and automatically avoids the rakes, or still gets to luck out in avoiding the rakes. Displacement guy takes a weighted average of 120.25 if the bite connects, much lower if it does not and he also avoids the grapple and stun. AC guy gets another 16-23 twice on top of his 17-27/17-27/10-25. His weighted average is 100.5, but he cannot reduce this and cannot avoid the grapple and stun.
If the character is good aligned the AC guy is taking another 17.5 average for an end result of 118. The Displacement guy is taking an 8.75 weighted average for an end result of 129. The Displacement guy will take less if the bite misses because it cannot rake and doesn't get the 7 average added from that.
Conclusion: A single 50% miss chance is enough to make a character who has not updated their mundane defenses since level 3 or 4 be comparable to or better than an AC specialist who devoted over one hundred fifty times more resources to the task against this creature. A less extreme example such as a character who had a few AC items and this Displacement would fare better, while still saving hundreds of thousands of gold. I see why the OP refers to miss chances as real defenses.
I forgot what stats were posted for the other creature, however I would expect very similar results were it tested.
