This is a gameplay problem. Players should use a tactic that gives them the best chance of winning, but if the tactic that gives you the best chance of winning is shieldrunning then something needs to be done about it. Both sides of the fight admitted that.
Snub guns should either have more damage or have more projectile speed. Freelancer PVP is about being fast and intense, when fights take up 90 minutes this is sort of lost.
