Just got my lock to 85. I have a question about the lock "rotation" in pvp. seems like the most popular build is the 31/7/3 build. Why do you get 3/3 Shadow and Flame instead of 3/3 Bane? Right now my SB cast time is 2.31, w/o the talent it'd almost be a 3 sec cast. Do locks just use drain life as the filler and only use SB on NF or corruption glyph procs?
