Alright, I went over all the gear plate/mail/leather. The thing to note is that there is a bunch of stuff with +defense thrown on it but it is a minimal amount compared to the difference in raw stats of other items. Basically all the items in the bracket with defensive stats are negligible to the defenses you get from offensive stats plus the extra offense makes them a better choice all around.
Example, boots of avoidance gives 2.5% more dodge and +.25% crit than AB boots, but AB boots have 11 str and +minor speed which means you can chant with +10 hit/+10crit (+1.3% to hit +.9%) vs +9 stam and minor speed.
Therefore 2.5% dodge and 9 stam compete against 11 str, 1.3% hit and +.65% crit. This is actually a bad example because it's a pretty good trade off but you will still need to hit the hit cap and prot. without minor speed is not cool.
I didn't chant the pants or the head because I believe they won't be available come 3.1 for 49s so I put on BoP pants that are pretty nice.
The exuberant amount of gear with surplus stats made me go for +def chants but you can always switch those around.
6 THOUSAND ARMOR (56.8% mit)
27% total mitigation from dodge, block, and parry. 6.48% to be missed and 1.48% not be crit
4.81% to hit (Yep I concur with everyone else that you should go for 4.9% hit because you cant defend yourself if your disarm, concussion blow, and thunderclap miss.)
17.62% to crit (I like to go about 15% mores okay
867 AP w/battle shout (AP is awesome for heavy hitting concussion blows, I love that post about not being able to take out a healer unless concussion blow is up, of course not but it's a 40 sec CD make sure you save it for them.)
226 Block value (might of went overboard with the enchant) but your shield slams should pone and they kind of need to, they cost a ton of rage.
3729 HP - This could maybe use some work...
This all seems pretty threatening, plenty of defenses with plenty of offenses are going to make for one mean soloing prot. warrior.
