It is a skill that comes with hours upon hours of dedicated practice. Something you obviously lack, or otherwise you wouldn’t be spewing nonsense like this.
Best widow doesn’t always win, rather it’s the team that enables their widow. The reason why widowmakers don’t go in teamchat is because people like you are the first to work against them rather than with them. It’s not just about aiming, it’s also about aiming while your entire team is verbally abusing you on solo ladder. Once a blue moon you’ll get a team that works with you to clean up kills (x hero half … etc). More often than not, you’re better off not joining the chat because of players like you.
In premades, widowmaker is often the one opening up fights or taking advantage of the chaos the tanks create and requires constant communication and coordination with her teammates. She is also used to bait the enemy into unfavorable engagements. This is something a frustrated little person like you wouldn’t understand, but would rather belittle others that have superior skills to you all the while failing to identify and rectify your own shortcomings. You are pathetic.
