Ahhh, wish I had more time to respond. One big thing, walk rather than run. My biggest issue initially was running to where the action was, and as a result right into bullets. Slow it down. If your teammates wanna run into carnage, let them and thank them for the assists after. Play support until you can play lead. Running into the action can result in some sweet plays, but the reward ain't worth it until you build your skill back up.
