With 64% RCR, you would take 1 - 64% = 36% of incoming damage, whereas with 28% RCR you’d take 72% damage. Your application of the formula is correct, but you fail to translate the gain in RCR to a gain in toughness. Even when CA does twice the overall damage of MS, your effective MS damage with the faster auto-fires, firing twice as fast, hitting baddies twice when below 60% health… you’re going to be doing way more damage with MS.

In addition to the auto-shots, the sentries will fire when you fire and since you’re firing MS twice as fast, so will they. The big difference comes when your character starts shooting MS.

Each of those MS casts are getting the damage increase from Yang and DML. Do it with CA and then switch to MS and you’ll notice a huge difference. Its easy to test this, run out somewhere and drop a sentry, time it for 30 seconds, and count how many times it casts an ability. Second, sentries will auto fire MS nearly twice as often as CA All of these will be separate sources, and combined together have diminishing returns on the damage. A character will still have armor, resistances, abilities like vengeance, items like wraps of clarity, elusive ring, unity ring. Without the yangs, the RCR is 28% and while 64% is more than twice 28% that doesn’t translate into 2x your toughness because its just 1 source of damage reduction. doesn’t count towards this since its not generic RCR Yang contributes to the total RCR, which is used for the damage reduction (CC set bonus) and that 50% has a big impact on RCR, but its also a diminishing impact. If you’re doing nothing but standing in town taking stuff on and off you could easily draw a very incorrect conclusion about Yangs-impact on your toughness and mistake it for “2x more toughness”. First, all sources of damage reduction results in diminishing returns.
