And thus, says Relmstein, the quicker abilities are becoming more powerful. Blind and Cyclone are the two main abilities he mentions, and both are extremely powerful in that they can be used by Rogues and Druids in conjunction with their escape abilities. And on the other side of the equation, Relmstein says that burst damage is king-- doing serious damage in between those moments where crowd control can stop you is critical. And that's why Warriors (and to an extent, he says, Hunters) are doing so well in the Arenas. When you can break out a ton of damage and debuffs during someone else's global cooldown, you're going to go a long way towards winning.
And it'll be interesting to see where this all goes in the future. With the recent changes to spell haste and the curving up of gear in the expansion, things are just going to get faster and faster-- players are going to be able to push out damage quicker and quicker, and crowd control will be more and more powerful.
