As for the set bonus; not the cost reduction, but the GCD reduction, assuming energy cap, is an extra 9 abilities per AR/SB (from 15 abilities at 12/.8 to 24 at 12/.5). That's huuuuge, especially as AR/SB becomes a shorter CD each tier to higher levels of haste allowing more offensive finishers between casts (and don't forget, longer SnD for yet more offensives from the 2p). If we assume you AR/SB every 100 seconds, and all of the added combo generators are SS, this is worth 7 SS damage, 2 eviscerates, and 5.4 additional CP - effectively, coming out of AR/SB, 7xSS damage and 3 eviscerates - which is 3 eviscerates of damage, and a full 30 seconds off the AR/SB cycle, which contributes hugely to auto-attack damage (although it's written as shadow blades)... per 100 (sorry, now 70) seconds. It's problematically powerful.
I'm baffled by Blizzard's decision to implement the set this way, but, well, there it is?
