You want to play a team FPS game but you want to have it feel like you are playing more of a single player game? Then Reaper is the closest choice for that. Reapers work a lot different than other heroes in Overwatch. Instead of sticking around your team's tank or healer, Reapers tend to go off on their own and have multiple purposes to fulfill, which includes: scout, harass, and ambush your enemy, usually without the help from other teammates. Reaper's offensive abilities allow him to seamlessly move around the map behind enemy lines and do quick surprise attacks and then reappear somewhere else to do more surprise attacks. Reapers excel at taking out tough defenses (Bastions & Widowmakers). As you can see, Reapers can really throw off the enemy making them more vulnerable to the rest of your team.
