This is what I use and I've found it to be extremely good once you have the correct gear for it. The gear needed is + lightning dmg, + blessed hammer, and + bombardment dmg. Currently I have + 29% lightning, + 10% blessed hammer, I have to drop my + bombardment dmg for better main stats but I will be looking to add once I get the correct piece. It's silly crusader is more gear dependent then other classes but trust me once you get the correct gear it does insane amounts of dmg with good survivability. I'm currently sitting at 855k DPS which isn't the highest but the burst allows me to I blow through T2 very easily. I don't have much issue with T3 it's just not as efficient as T2 in terms of speed.
The reason why I chose the skills is because they all work together to provide huge burst every 45 secs and good dps increase every 20. When I get to an elite pack I pop 1, 2, 3, 4 and just spam the fuck out of hammer. If bombardment crits they die instantly if it doesn't crit then by the time my wrath is out everything is dead. In Rifts when Rift boss spawns I do the same thing with popping 1 and 4 every 20 sec. The passives I chose are finery because I have 5 sockets, blunt is obviously 20% more dmg to both my main dmg abilities, heavenly str that's obvious too (they really should just make this baked into the class), and righteousness because with it im at 138 wrath which gives me plenty of wrath to spam blessed hammer to clean up elite packs if bombardment doesn't crit.
