Can’t say I agree with some parts of your build:
warder is quite possibly the best HC class if built right. i can’t think of any class thats tankier. why forgo ur biggest advantage - OP heart of the wild/military conditioning.
getting warcry at lvl 10 doenst make sense, it scales harder the higher it is due to subtraction nature of it. also it needs a cast so either no points or max. getting it half assed is like wasting ur casts.
if you’re stretched on points i’d consider using a kymon’s enchant over warcry, it does the samething mostly as long as ur hitting for 100% or more weapon dmg aoe, which u are.
why max storm surge, its literally terrible compared to how much lightnign dmg u are getting from a lvl 26 PS plus torrent. its so minimal, u could really use the points elsewhere. the bleed dmg/+physic are mostly useless since ur going lightning.
devotions - u feel squishy at times, because you have low autoheal. no tree of life and no wendigo totem; wendigo is super good, but if you really can’t afford the skill points, then you should get tree of life. chariot isn’t that good honestly. you have no -enemy resist. either get arcane bomb or rowans since u arent going wind devil. cool effects everywhere doenst make u strong, -resist does, reckless tempest isn’t that good.
scars of battle - this scales just as good post lvl 8/8 , why keep at 8? get as much as you need.
decorated soldier - 8 points for the 20 or so ele resist and a small amount of slow isn’t worth it if ur low on points. ele resist is so easily obtained from gear.
eye of the storm isn’t a no brainer… since you have literally no -resist. using malediction will DRASTICALLY out dmg eye of the storm. trust me.
not to be harsh but i don’t think ur build is very good at end game content even though it should be with such a powerful class. but please do prove me wrong with some gameplay vids i’d love to see a BoC clear or fabius kill.
edit - just saw ur blessed steel, its single target and needs a cast tho, kinda meh, not sure if i’d take taht over rhowans or winddevil. would still take arcane bomb over reckless tempest anyday
