Actually Holy ain’t that bad outside of ease of multipliers for Holy damage vs Fire (you can get holy on amulet and bracers and that’s about it, don’t think you can get holy dmg on rings). The shattered 3 pieces also benefit fully from all your dmg buffs / multipliers and they count as a normal BS thrown, also each bouncing 6 times, so your BS dmg increase counter will go and stay up insanely fast compared to fire with some mob density. It also melts elite packs that stay close (not like the ones who spread in all directions shooting etc), I can pretty much drop elite packs in 105 in like 5-6 seconds if there’s like 5+ mobs nearby. It makes it at times not even worth to move to triune / follower dmg ring because it will be a dps loss.
Also with Gogok and having perma uptime on both Laws of Valor critical and Provoke for extra 50% block (am peaking 79% cooldown reduction with fully stacked gogok) and iron skin, the dps increase and toughness / safety should overpass BotT IMHO (extra attack speed and 50% crit dmg on top of always having 100% block chance for BS dmg multipliers irrelevant of your CoE cycle).
Sure fire can most likely burst harder during CoE cycle, but I feel that Holy has better all time DPS and more flexibility.
PS: stonegauntlets sucks vs slow hitting RG’s like Butcher, you will never get more than 1 stack - which while it’s good, it won’t save you from getting KO outside of your iron skin / Akk Champ. When I did couple 115’s with a pug (was pretty much a Vyr’s 3k paragon wiz doing all the dmg) I swapped my stricken to Esoteric and BS physical for armor stacking, I was peaking 3.6B toughness and facetank in molten / beams / plague etc, also running ESO in cube for the pull so I can stack mobs on top of the archon, it was freaking epic!
