Please don't be too heavy-handed with any sniper adjustments

Also to elaborate a bit more, weapons not having as much spread in this game means it's very easy to fight back against a sniper if they miss 1 shot than most prior titles. Some might think that's a good thing, but it's also worth remembering that those full-auto weapons have a massive advantage in every other engagement as well, so. 

Imo they just need to delete the range finder because it's goofy and the cheese you can do with it strips out all skill when it comes to incredibly long range.

You make some good points, although when it comes to maps, I do want to point out that your picked your example: the smaller urban maps are not sniper-friendly, but plenty others really are. For me, my enjoyment of Liberation Peak is directly proportional to the number of snipers playing mountain goats. 

However, I want to put it differently: it is not about snipers being overpowered. In fact, I can't count the number of matches that I am certain were lost because one team had too many snipers unwilling to change their play style when things started going wrong.

Which is kind of the crux of the problem: they made snipers so easy to play that too many people want to do it. That it does not win the match, or even allow you to do well on the scoreboard, is kind of moot, it kills team play and makes for a very unfun environment.

And on the fun aspect, there needs to be a better balance. The current mechanics are there to make sniping more fun to those who use it. But it's also miserable to everyone else, whether that sniper is highly successful or not. The fun of darting from cover to cover and keeping your nose in the mud the rest of the time has a short expiration date. Sure, dying is never fun, and there are plenty of ways of dying in miserable ways with no counters: spawning in front of a tank, getting blasted by a helicopter you never saw or heard... All of this is part of the game. But there needs to be a balance on how often this is going to happen.

And right now, with so many players in each team going for sniping, it really happens way too much, especially when compared to older titles. And it is especially frustrating when you know those kills took very little skill (and we all know that, because we all tried it, and I've had some of my best KDRs when sniping). An earned kill is a much less frustrating death. When it's a one-sided engagement with no available counter, that skill requirement is essential, or it just feels bad.

Sniping should not become exclusive, but it needs to become considerably less casual. If you're going to be given a tool that lets you delete people from the other side of the map, it's absolutely fair that that tool should require efforts to use properly. Right now, I think we're in a pretty bad place in that regard. 

I think you aren't really remembering past Battlefield titles if you think snipers being this way is contributing to too many snipers. It was not uncommon in past titles like BF4, BF3, where snipers had WAY lower velocity, no range finder, slower fire rate, etc. etc. to have teams with a bunch of useless snipers. You're thinking of it completely backwards. 

There will ALWAYS be useless snipers doing nothing. Making sniping more approachable means they might actually contribute something every once in a while! That's a good thing. The strength of snipers is not cleanly correlated to the number of people choosing to snipe.
