Fake or Assassinate?!

One of my alliancemates spams assassinate and boomstep to train, and she said that fake and high avoid really complement assassinate, so I would suggest getting max fake first. Assassinate doesn't have any invincibility period, so fake would probably really nice for coming out of dark sight and not taking damage. She also chains up dark sight, then assassinate, then boomstep into a macro, which lets her use boomstep right after assassinate while canceling assassinate's last hit. If you don't get hit coming out of dark sight, you won't have to use a potion and break the macro. The extra levels it takes to max assassinate also helps your natural avoid.
