these build works back at 2.0. since new patch coming out, we shall see what will be best soon

cant answer that lol coz b4 gr started i already 500+. and nothing to do with your paragon lvl mate, right gear right spec right skill will easily take u over 35gr solo

with shield bash build i'm hitting 600m + dps aoe burst consistently.

my crits go between 1-2 billion dps.

my regular attacks are also quite fast due to abilities, so i benefit from faster wrath regen and life per hit somewhat (though i'm not really focusing on this too much, except to reduce my cooldown for abilities by hitting faster)

my blood brothers weapon + shield + hellfire amulet (stand your ground) increases my block chance up to 50% The weapon effect, everytime i successfully block, reduce that damage by 30% also, increase my next damage attack by 30% 

using the recommended focus and restraint rings for their op effect for damage increase.

For belt i use string of ears for melee damage reduction.

a full set of rolands gear

a piro mela shield for cost reduction using shield bash
I recommend getting these stats for shield bash build

- helm (chc, str,shield bash, socket)

- shoulder (str,vit, ares,cdr)

glove (str,vit,chd,chc)

chest (str,vit,ares,socket)

pants (str, vit, ares,socket)

boots (str, vit, ares, shield bash)

shield (str,vit,chc,shield bash)

belt (str,vit,life,ares, dmg reduction)

bracer (str, vit, ares, fire dmg)

amulet (fire dmg, chd,chc, socket) *preferably etlich with rng dmg reduction. Other strong contenders hellfire with stand your ground.

rings (str, chd, chc, socket) *preferably focus with restraint set rings

weapon (10% DMG, str, vit, socket) *preferably blood brothers, also ancient version
the only downside i see so far is that akkarat champion (prophet) cooldown is not quite good. Without it, you won't be able to spam shield bash for long, also your dmg output as well as survivability drops alot. So you end up waiting around for akkarat champ to be ready. This is a big problem for higher grifts, where you can't afford much downtime. But the thing is where would you fit in CDR into this build to improve on that ? From what i heard you only need 30 cdr roughly for the build to work. Not sure if that is true or necessarily enough 

if want to maximize BB, then i recommend hellfire with stand your ground, or alternatively a passive that you would use in your bb build, so you got an extra slot to add in stand your ground.

Alternatively, instead of the hellfire amulet, you would have to then instead roll in str,block chance%, chc, shield bash into your piro shield. The upside is you can use another amulet e.g. xephirians, etlich or other. The downside is your now missing a huge chunk of vitality which you would normally have. So don't do the 2nd approach if your HP drops down too much.

Alternative to BB, the furnace is also very good because of the 50% elite damage. I have an ancient version with 48%    So because it doesn't rely on block, i can safely ignore that.
You make a good point about akkarat's champion..... yes it's core because it minimizes a huge chunk of dmg intake from minions/elites. Not to mention you also can spam shield bash while it is active.

in a SB build cdr isn't maxed to the full like a zdps. However the dillema is, akkarats champ relies on faster cooldown for you to be able to use this as soon as possible. I heard that 30% is the recommended minimum cdr for this fire sb build. But it still feels like more would be useful, but where to add the cdr from ?

8 shoulder, 2 rings.

The rings would be like 8cdr/50chd/6/chc/socket (so no str basically). Though i probably would have 2nd thoughts on that if it were ancient version of FR 

amulet you wouldn't because you'd want fire element/100chd/10chc/socket. The only possibility of cramming in the extra 8cdr ontop of that is the time amulet, which downside is no special ability like elemental immunity or dmg reduction.

weapon and shield have a huge chunk of vit, so is a bit hard to justify adding in the cdr there, especially if those pieces were ancient.

then belt vigilante belt versus string of ears. you'd want more tanky for higher grifts.

helm you can't use leoric's crown with a diamond, because that would mean using a RORG which you can't because your go to rings are the F&R.
so bottomline cdr in shoulders, and maybe even rings if you can add them after getting chd/chc/socket. And last resort into amulet only if it's a timeless ideally.

i think the LoN set is much than the class set in my opinion 

it's all ancient gear booster set , mostly uses for thorns and blessed shield build but can be experimented with other skills as well but haven really try it la   

with proper playstyle, RNG, gems level etc, Invoker still can do 80++ but LoN generally better..
