Overwatch Team > Riot Team
I play both Overwatch & League and I enjoy both very equally, but when it comes to which team is more respecting towards their community, the Overwatch team EASILY win that one.
Because almost every week, Jeff Kaplan (Vice president of Blizzard Games) uploads a video onto youtube explaining the upcoming changes in the game AND addressing user suggestions, and complaints that users have been having.
Whevener I read or watch one of those /dev things that riot always upload, it always seems like they're advertising the game more than really evaluating it. They always talk about how "Exciting the upcoming changes will be" but almost never ever ever address the NEGATIVES that League has been facing, such as towers.
Step it up, Riot games. League has been around 5 times longer than Overwatch has, this is very amateur.
