2pc: 24% damage increase to blade dance(20% crit on an ability which does 120% crit damage), which with first blood hits slightly harder than a chaos strike. So, basically, once every 7-8 seconds you get a half-cost chaos strike that does 24% extra damage.
4pc: every time you blade dance, you get 2/3 of a chaos strike worth of fury(average fury cost of chaos strike at 50% crit rate is 30). Or, looked at another way, you get one extra chaos strike every 10-11ish seconds based on haste.
so, all in all, in a 45 second window, you're gaining roughly 2 chaos strikes worth of damage from the 2pc, and roughly 4 chaos strikes worth of fury from the 4pc, both of which scale very favorably with haste and gear in general.
T21 -
2pc: eye beam deals 30% extra damage. Eye beam's actual base damage does almost identical damage to chaos strike, except it does not scale with the best artifact trait that we are itemizing for so it scales much worse. But for the sake of argument, lets say 1 eye beam = 1 chaos strike, on average. This means once every 45 seconds, you get approximately 1/3 of an extra chaos strike worth of damage.
4pc: 15% haste for 8 seconds after eye beam. This is just garbage, its 10% less haste than meta, and even 5% less haste than a sephuz proc. 15% haste for 8 seconds, after diminishing returns, is ROUGHLY one extra GCD/auto attack. so, one extra gcd every 45 seconds.
just comparing the two in terms of our made up currency of chaos strikes:
t20 gives you: approximately 2 chaos strikes worth of damage from the 2pc, and 4-5 chaos strikes worth of damage from the 4pc, both scale very favorably with haste, for a total of, lets say, 6 extra chaos strikes worth of damage in a 45 second window.
T21 gives you: 2pc gives you 1/3 of a chaos strike, and 4pc gives you one extra gcd, lets call it a chaos strike assuming no resource starvation, every 45 seconds. so, 1 1/3 extra chaos strikes every 45 seconds.
conclusion: the t21 set bonuses are approximately 5x worse than the current set bonuses, and scale very unfavorably with stats in general. eye beam does not scale with crit, our best stat, or haste, or second best stat, while blade dance and chaos strike scale very well with both. The 2pc bonues, in comparison, are: roughly 8 extra chaos strikes versus 1/3 of a chaos strike, which is 26x worse. the 4pc of t21 is likely to do almost nothing most of the time, as it will be up during meta or bloodlust a good chunk of the time and amount to a tiny amount of extra haste after gear + bloodlust/meta, making its value actually less than i generously predicted it at being.
Since set bonuses make up a much larger contribution than ilvl increases, particularly given that secondaries scale particularly poorly with ilvl, and are way more valuable than agi, it's likely that you'd need a very, very large ilvl increase on your t21 gear to make it better than old t20 gear. With titanforging and all that, my guess is unless these set bonuses see some major, major buffs or reworks, we'll be going back to TOS to get t20 gear for the entire tier. More likely, bliz will just nerf the crap out of t21 and force us to use their awful new tier set bonuses. Even more troubling is the nature of these set bonus changes, which include nothing that generates or discounts resources, like generating 20 fury on a blade dance or making blade dance a really good button to press at a discounted 15 fury, so we are likely to have serious resource starvation issues once again in t21 which, more so than any damage gains/losses, will make the playstyle way more awful.
