I have a PC Bodyguard in my game that has Barrage (2 ranks tight now) and this Talent just doesn't seem to come up too often, Usually it's because of one or more of the following reasons:
1) The terrain doesn't support the encounter being at Long or Extreme range (the interior of buildings and/or starships).
2) The encounter doesn't support the character(s) carrying around Ranged (Heavy) and/or Gunnery weapons, especially those that can actually be used at Long+ ranges (encounters in a populated and civilized areas).
3) The groups close range very quickly (usually to allow melee and/or pistol users on both sides to engage).
OTOH, and for the inverse of the above reasons, Point Blank seems abnormally easy to get consistent use out of. Any suggestions for helping out Barrage that don't look artificially forced?
