Hmm…
So, let’s start with this: I’ll grant you the “more toughness”. That seems like a given, between using S+B, the shield itself, and doubled War Cry.
But, I really don’t think you’re going to be doing more damage. Let’s look at some numbers:
Basshead’s proposed setup with IB will attack faster, most of the time. This S+B setup will reasonably range in frame rate between 18F and 10F, depending on how many EF and PE stacks you have. The IB setup will range between 12F and 14F. It’s not unreasonable to just take the midpoint in each case, since you obviously can’t keep up all those stacks, all the time. So that’s 13F average for IB, and 14F for S+B, or a 1.07x speed multiplier for IB.
You also have:
1.3x IB damage
1.5x CoE damage
1.19x damage due to higher crits (this takes into account both significantly higher CHD, and slightly lower CHC)
1.15x damage from Rampage (a rough estimate based on how many stacks you can keep up, on average)
1.0x multiplier from Brawler (basically a wash with S+B’s doubled BR dibs)
So that’s a 2.85x multiplier, total.
The S+B setup has:
1x-2x damage, depending on CC uptime on mobs
1.04x higher weapon damage
1.14x higher elemental damage
That would give you up to a 2.37x multiplier, total, assuming you could keep up 100% CC uptime on your enemies. But that is obviously impossible. In reality, depending on whether you use Cold Rush, Ground Stomp, fear/stun/freeze on armor, or a combination of all of those, you can keep more or less 100% CC uptime only for the first 7-8 seconds of the fight, after that your uptime drops to 25-27%. If you assume you can get in a big burst of damage right at the start of a fight with a densely packed bunch of mobs, I think you could estimate the H90 2-piece multiplier at 1.5x, if you are being VERY charitable (more likely it is between 1.3 and 1.4).
So: actual (generous) multiplier for this option is 1.5 * 1.04 * 1.14 = 1.78x
That means the IB setup has a damage “base” about 60% higher than the S+B setup.
You do have doubled Bloodshed with S+B, which is great. But because your damage base is considerably lower, you only end up doing about 25% more damage via Bloodshed. The IB setup does a lot more damage via AD: about 64% more.
All told, when fighting in good density you can expect to do at least 22% more total damage using the IB setup. You’ll also kill RGs faster, particularly single-target ones, in which case, with neither setup being able to use PE or EF, your speed advantage with IB will grow from 1.07x to 1.29x, which basically “double-dips” because you not only do damage faster, you also stack Stricken faster.
You’re also going to have some mechanical issues with the setup you have here. If you don’t take Charge, even all that added toughness may not save you in a high push when you’re pinned in place and multiple molten explosions go off in your face. You also might just get stuck fighting right next to, rather than inside, an Oculus circle, with no way to reach it.
If on the other hand you take Cold Rush, you don’t have enough CDR here to keep up 100% uptime on BoM, which is obviously not ideal. You can also only reposition once every 9 seconds, which means you still might get blown up by molten or miss out on a juicy Oculus.
Anyway: all this said, this looks like a fun setup. If you can record video, I’d love to see some of your gameplay.
