Actually, leave flares as they are. It will raise their price and make them a good trading commodity. Those who will want to use them at their own bases will have to pay a bit more, and those who will want to lurk people (mostly newbies) into encounters, will actually have to dish out some caps to supply themselves with them. This will also limit the amount of red bait encounters, and will provide more focus PvP if some organized group enters it.
Don't change anything!
