The Osti shake is WAAAYYY overdone, and Flayd is right, the shake snychs with a .50 cal, not a 37 mm firing a round about 3 times every 2 seconds.
There was a good reason real planes would not fly anywhere near a real osti unless it's guns were racked to the maintenance position. To do so meant you were going to be a flying piece of swiss cheese, no doubt about it.
I also don't think modifcations ought to be done to compensate for people who take the time and effort to become masters of one aspect of legitimate game play - like the LTARs in Ostis. Most people could not go get 7 or 9 kills in a tempest in one sortie, so do we have to dumb down the tempest because some people can?
What IS the purpose of having an Osti in the first place? Isn't it to pose a threat to airplanes close in to the field when ack goes down? What's the point of having them if they DON'T pose much of a threat? The whole concept of a strategic game is to make it so just when you think you have it wired, the other guy can slam the brakes on your "piece of cake" operation, forcing you to figure a way around it. There are plenty of ways around an Osti without making it so docile any plane can casually sweep by and toast it with a single strafe.
