Are role actions a nerf?

[Shougun]

Apparently it looks like bloodbath, mercy stroke are gone. It does seem like a nerf, but many things were rebalanced so we wont know until patch day.

I was wondering if perhaps Warrior gets more mitigation abilities through their consumption of wrath/damage and Dark Knight would then get more/powerful blood magic.. Perhaps they're breaking up their themes a little more. I mean their bar is called the "Blood Gauge" lol.
