I have a... maybe stupid - if so, do call me out! - idea for how to address making this a blind buff to snipers.
What if the first or second round of a bolt action's mag is a tracer only?
That way they could still retain some sort of benefit, but not without having to engage with tracers.
Either you game it out and chuck a round in the dirt - which I'd assume folks MIGHT do.. it's a vidya game, folks optimize the fun out of it lol - if it's the first round.
Otherwise, you could just fire one round, and give yourself a MUCH slower bolting... because you'd load a new mag every shot.. but you get to be fully concealed. Give/take.
Ideas, comments, concerns? ๐ค
