Nothing has changed with Old Standby, but its still our highest single target damage spec. This pony only has one trick, but its a good one.
Pros: Highest single target damage
Cons: Very poor AOE, no utility, requires melee range
This spec still has a difficult rotation and I strongly encourage you to get nkRebuff (or a similar add-on) if you’re going to try it. You need to track and keep the following buffs/debuffs active, in order of precedence:
Make sure Stalker Phase is up when you use a finisher, and only apply EW manually when you use Annihilation. Otherwise, apply EW with 5-point Assassin finishers. Don’t let Annihilation or Impale fall off, if you can possibly avoid it. The entire spec is really just a game of whack-a-mole with your buffs and debuffs.
