I always thought that the Ghost Summoner Spell was essentially the more "noob" version of Flash. Recently, however, I have seen several pro-level games (MLG, PAX, etc.) where the pros do indeed get
Ghost instead of
Flash. I don't understand the logic behind this and was hoping someone could enlighten me. I've seen it a couple times, but the champion I specifically remember it on was a Shen.
The only thing I could think of was that Shen can already use
Taunt to get over walls and obstacles, so perhaps
Ghost would generate more distance in the long run... But even this seems like a stretch.
