As a sniper, there are many things that affect the trajectory of bullets. The major forces that change the trajectory are Gravity, Drag, and Breathing. Gravity naturally pulls the bullet to the ground. Drag is caused by several factors as well (some won't be feasible in-game). Difference in termperature, barometric pressure, humidity, and wind push the bullet around on its way to the target.
Of the real-world factors that play their part, Gravity, Breathing, and time of flight are the most feasible in the game world.
A few interesting things to add would be improvements to breathing, addition of wind, and accurate time of flight (if it isn't already there).
Normal breathing should be around a 5-7 second cycle. 2-3 seconds to breath in and out, 3-4 seconds in between. A button to hold your breath for 8 seconds would be a nice addition as well.
Wind would greatly enhance the sniping experience. Wind direction could vary per map as well as wind velocity. This could also apply to tank shells (to a certain extent). Generally, a 5mph horizontal wind will move a round around 3in at 300m and 7.5in at 500m. 5mph diagonal wind moves the bullet roughly 1.3in at 300m and 3.8in at 500m. This is just an example of course, in-game the adjustments do not need to be precise. It just shows how interesting the ballistics can be.
If time of flight isn't already calculated, it could also make sniping more interesting, however, I'm not sure if it would be worth the extra load unless shots could be taken between 400-1000m. For example, a 7.62mm round takes around 1 second to hit its target at 700m and 1.8 seconds at 1000 yards. This may or may not be fun in the end because people tend to run all over the place in games and it may just end up being frustrating. That, and I'm sure lag already plays a part.
Another interesting addition could be a vapor trail. Before anyone jumps to conclusions, hear me out. Farcry made snipers look like they were shooting tiny RPGs for bullets and using flashlights for scopes. Vapor trails aren't ridiculously obvious, but they could give the sniper an idea where to place follow-up shots. And, I can't deny, it would look pretty cool.
Hopefully you read most, if not all of this post. If you disagree, please do so in a mature manner. If you agree, let me know. Feel free to add upon these suggestions if you feel you can make them better.

Sounds great on paper and gives Zaitsev-fans a stiffy, but in the context of the game these things would be unpractical.
