Also a lot of those shots in your video were fully charged body shots which are obviously pretty easy to kill enemies with, but in more dynamic maps you are rarely going to have the opportunity to build up a fully charged shot and still be an asset to your team. Try sniping on more dynamic maps where there is more of a push and pull such as granary or gravelpit or badlands, because when you are in a situation where there is actual pressure to kill the enemy it becomes much harder to win. It's easy to snipe players who pose no threat to you which happens all the time in 2Fort since it is a stalemate map.
