Balancing idea: optimize global behavior/logic/whatever to prevent enemies snipering from miles away

[Aceearly1993]

This is especially bad in the skeleton gunman section in Guernon University in Ring of Fury mode. Skeleton gunmen snipers from so far away that the windows of reaction is close to none at all.

I'm not sure if it's because skeleton gunman himself is designed badly or something else, but the animation of skeleton gunmen also need some tweaks to be in line with the thing in LC1. In LC2 his gun fires too quick before the frames of him rising the gun fully played, and did not sync with his animations well.
