Currently it’s mostly tankers who get it (at least from my experience) and imo it feels a bit cheated. It’s easy to get ranged master when you have an indicator exactly where your shell will land. And tanks already have other badges they can get so taking away one of them won’t do much harm.
Meanwhile actual snipers have to show some skill in long range shots than just lobing 50mm HE shell at the indicator. It would slightly increase snipers effectiveness in terms of XP gain.
