My current generic steel path build.
[Primed Firestorm] can damage and proc through walls so it's vital for large hordes of enemies. Note: Must use the Primed version given the normal gold sucks.
Replacing [Primed Firestorm] for a Bane mod will increase Burst DPS by 640k.
Replacing it with [Serration] will increase Burst DPS by 382k.
[Bladed Rounds] is preferred over [Hammer Shot] due to the lack of status procs, and [Hunter Munitions] does the work for me.
Also, due to my riven, crit damage is preferred over other damage.
Replacing [Firestorm] with [Serration] and [Bladed Rounds] with a Primed Bane mod will increase damage by 560k. Therefore [Bladed Rounds] is prefferable over [Serration].
If you want pure damage, (2mil+ Burst DPS), [Firestorm] and [Hunter Munitions] can be replaced with [Serration] and a Primed Bane mod, but is very map specific.
Overall, this build is my personal favourite as large amounts of damage is not as preferable over using [Firestorm], as it's utility is much more appreciated.
p.s. I also can't be bothered mod changing all the time so I keep to this
