Season 13 is almost there so here's a complete breakdown and overview for ALL BEST possible Crusader Builds out there. I went through all of them during PTR, both old and new, and trust me, this season will be glorious for all Crusaders out there. If you never played the class, never tried Condemn of Holy Shotgun, Sweeper or Thorns, now is the time. I think that crusader might have the most diverse build variety out there with nearly every build reaching GR100 and above.
All builds here, as usual: http://www.angryroleplayer.com/diablo-3-builds/crusader-builds/
1) Roland's Blazing/Lightning Sweeper GR100+
2) Holy Hammerdin GR100+
3) Thorns of the Invoker GR100+
4) Akkhan Condemn GR100+
5) Akkhan Blessed Shield GR100+
6) Akkhan Holy Machinegin GR100+
7) Akkhan Invoker V2.0 “MELEE BOMBER” GR100+
For speedfarming i think Condemn might be the best this season, and i also developed my own build for this, check it out:
Reliable 2-3 mins clears gathering all legs and DBs with under 2 mill dps. Pretty damn good.
Norvald is just as viable as before, even better:
