Generally hitscan is as much skill as opening up the start bar. It takes alot to make hit scan a skill, which in 2k4 frankly there's alot. All the movement and associated latency means that the genuinely hard shots are skill, there are the odd hard targets (moving xlocs) but generally the idea that you can shoot someone a couple of times down a hallway being skillful is retarded. If you're picking off someone's head whilst in mid air and they're dodgjumping down some platform, then yeah, there's alot of movement & prediction in that, added to latency and you have a prediction shot which is, essentially, not hitscan.
So IG fanbois saying that hitscan is pure skill, nah. The skill comes from much more than point & click.
