The thing is when your making a shield bash build (Lord Commander Build) you also have to look at what affixes you can get on your gear and 15% spell dmg (Shield Bash) on the shield is worth more then 11% block this also translates to other stats like on rings and helms which results in block chance just being useless as a affix to increase the dmg of shield bash.
Rings: Physical SoJ Eternal Union (eternal union is because it will make your phalanx last for double the time)
Amulet: Any physical legendary amulet with a trifecta roll so physical cc cd.
Skill Build (Law Of Valor is interchangeable to which ever-other Law or rune )
Weapon of Choice is Baleful Remnant
TL:DR you made nothing new just a bad version of lord commander build that will only get you in t6 with a unity. Now im not saying that the build is bad just that there are better builds then it that utilise the skill shield bash more effectively.
