I think the biggest thing I can think of is that EoR isn’t a default weapon attack. You’ve got points and devotions invested into Weapon Proc Skills (WPS) and they’re only going to be activating when you aren’t using EoR.
Check out sir_spanksalot’s DW Warborn warlord for an endgame build.
One thing that sticks out is that DW gives you a lot more damage than S&S. Also, keep an eye out for green gear that helps fill out resistances at this point. Get yourself a blueprint for Stoneplate Greaves and craft a few hundred, even one good affix will increase your resistances a ton.
