Sorry for interrupting your extremely interesting discussion, however, Gang is completely correct. It is not that hard to target a person when you are prepared for his invis+recall but when it comes to a real fight you will hardly have the time to do so. In addition to having lightning reflexes in order to cast FF on the invised dude you must not be casting anything during this time (and your opponent can easily inv+recall while you cast FS), there must not be any obstacle which can brake LOS or make it harder to target the tile where the dude is (think of chasing a guy into a forest). Moreover, this should be a 1v1 fight because in gangVgang scenario it is even more difficult when you need to play defensively.
