I haven't looked at the gear yet because my work computer blocks the site but im wondering why you favored STR + Block value more so than hit and expertise? Block value will only increase the threat of SS which is one skill. Hit/Expertise will allow all attacks to land thus increasing threat not just Shield Slam. Haste also doesn't do much for us because all our skills are instant attacks. It might bring in a bit more threat on Heroic strikes and swings but not that much and it expensive to stack as a warrior not making it very worthwhile.
