I'm not very happy with how the rogue talents turned out in Mists. Rather than new utility or cool features, we saw our old abilities given back to us, except that they were made mutually exclusive. The level 90 tier was particularly disappointing, as it focused on improving our quality of life instead of adding new functionality. Paladins get Boundless Conviction for free, and yet we're paying for Anticipation. I have yet to meet someone using Versatility. Couldn't we just see Redirect's base CD lowered to 30 seconds and call it even?
The worst talent of the bunch seems to be Shuriken Toss. Why would you use an ability that's significantly weaker than Mutilate? The surprise is that assassination rogues don't care about how much damage Mutilate does; mutilate is only their 7th-highest source of damage. Shuriken Toss, on the other hand, generates more combo points per energy than Mutilate. Shuriken Toss still procs Deadly Poison, which makes up 40% of our overall damage. Rogues across a variety of gear levels are reporting Shuriken Toss results that are at or near Mutilate's performance. Update: Due to last night's PTR updates, Shuriken Toss will no longer proc Seal Fate when in melee range. As such, Shuriken Toss will not be viable after patch 5.1 goes live.
