I think they’re doing things a bit at a time. Most of the changes listed here seem to be to address cheese play, with the exception of the Lurker (the Nydus Worm creep change is to allow Queens to be able to transfuse the Nydus Worm the instant they pop out). Ghosts aren’t really a cheese unit (although there’s some nice 1-base Marine/Ghost All-Ins for TvP).
I hope some late-game PTR patches will come later, and I sense Ghosts may require a bit more thought. I have my own suggestion where PvT is concerned ([Suggestion] Protoss late-game (Templar + Tempest)) - ZvT I’m not completely sure about, although an overall reduction in casting range for EMP might be a thought, but I’m guessing the problem is that they can counter all Hive-tech units too easily with Steady Targetting.
