That was just simply.
*MCP have ability to reduce his attack speed per 50%. It works 3-times, so you can burst one mcp per 90 sec. We used counterweight as cheap enchant.
*Then use it with spell power gear. You should get ~700 sp from gear and consumables.
*Use both physical and spell consumables.
*Use as many on hit consumables as possible 
*Mix it with haste enchants and haste trinkets…
SoR damage isn’t reduced by haste effect and do not scale with weapon damage like SoC, so every 0.94 sec SoR doing the same damage with MCP like with 2.00 speed.
MCP is 2H Mace so works perfectly with Human Retpaladin Then calculate that SoR damage with 700 SP. Add other spells buffed with SP, some consumables that scale with SP and you can create Holy Minigun that shine on the battlefield like Christmas Tree with all that “on hit” effects xD
