I've started to use Snipers in Destiny just recently because I got my hands on Patience and Time. I really enjoy using that sniper a lot. Using a Sniper with a larger magazine seems to be a better choice for me currently because of my inexperience with snipers. Thats my first tip for you, use a Sniper that has a larger magazine. Make sure you have a good primary to switch to in case someone gets close to you, because it will happen and that person will probably have a shotgun because its the Crucible. My last tip is be patient sniping in Destiny, its not run and gun like it is in Halo.
