The big news from WWI so far for rogues is focused around two things: picking up a little AE damage and getting more use out of Sap. Both hints came from Tom Chilton during this morning's WWI dev panel, when he spoke to a large swath of class changes and balance issues.
The inspiration for the new area effect damage ability comes from Warcraft's Wardens -- Fan of Knives. As part of Blizzard's attempt to bring the lore and history of the game forward, they look to previous abilities and lore to inform current changes. Fan of Knives seemed like a natural ability to help give rogues a little extra AE damage. While Chilton cautions us not to expect Rogues to become the kings of AE damage...this will may be a welcome addition to our bags of tricks. It could certainly help in a pinch, but we'll have to see how it's going to meld with crowd control powers.
Where Rogues should feel some relief is the additional consideration given to Sap. Chilton's looking for Sap to play a greater role in crowd control strategies, and having it apply to more mobs. To paraphrase, Sap's going to apply to anything with a skull, and a brain to then rattle around inside of it. We may see ourselves sapping dogs, cats, bears, and. . .well anything with a brain inside a skull. So maybe not oozes quite yet - we're just going to have to satisfy ourselves with killing those.
I think a lot of the Rogue information we're curious about will actually come up during tomorrow's PvP section, since it's the Rogue's Arena capabilities that's seen so much forum action lately. Like Mages, we just haven't gotten the same amount of screen time as Death Knights or Shamans. Still, here's hoping we see more soon.
