Why overwatch if you want to be cybersportsman? Isn't quake better for this? For me overwatch seems overhiped and too random.
Your choice anyway but I hope you know what you are doing, you will have to play this game for years on each character on each map knowing every mechanic the game has. Any game will become boring especially overwatch with its limited content.
Thank you for your feedback the reason why I chose Overwatch is because I know I could improve myself into it, and do my best to reach my dreams. I have not played quake yet but i've tried different games such as Dota but I lost my passion to it because of the community.
Yeah dota community is special I know that. Quake and probably starcraft are games that require most skill in my opinion but I am saying that as someone who had very little experience there. Goodluck with overwatch if you are confident about it.
