Haven't used the new techniques too much yet, but I agree that the lunge attack should provoke attacks of opportunity and should use movement. Maybe that was an oversight that will be corrected in a hotfix or new patch?
Also, I definitely appreciate giving melee characters more options, but kinda wonder if it makes Battle Master Fighters less appealing. The only argument I have against that is the additional restrictions on the new techniques (once per short rest and weapon specific).
