Diablo III: Reaper of Souls

Marauders got buffed? I missed that somewhere, what exactly were the changes for that?

I see the sentry hatred spender change but does that mean that they cast really fast now? Or... what's the deal here lol

On Live, Full Marauder's bonus makes Sentry's not use their correct attack speed if you use Elemental Arrow or Chakram on your bar, or Multishot + Impale. Sentry needs to fire a regular bolt to set its correctly scaled attack speed. It doesn't affect Cluster Arrow + Multishot since there is enough cooldown between skills to shoot that bolt. Elemental Arrow and Chakram replace every bolt. Impale and Multishot can alternate without a bolt coming out. With this change, you can replace the (now 280%) Bolts with Elemental Arrow, Chakram, or Impale and still keep the correct attack speed. The default attack speed is 54 frames, and with max attack speed, it can be down to 12 frames, though typical non T&T 1H would be around 30 to 24 frames, as opposed to the optimal 2H Crossbow of 42 frames per shot.

It also might mean that 1H Crossbows and Bows may be competitive with 2H. From what I calculated myself, equally well rolled 2H beats the 1H and Bow because the attack speed doesn't scale well enough, given how little damage regular bolts did.
