Let's Talk About Competitive Teams, Specifically Player Roles.

So in other games, the competitive scenes have designated roles for each player on the team. CSGO: Awper Lurker, ect. Overwatch: Tank, Offensive, Flex. League of Legends: Top Jungle Mid ADC Support.

So my question is, what do you guys think that the player roles on competitive teams will be? Players who play only by faction, only by Hero Type? Keyword, or even just people who know how to play what's strong?

Let's hear your thoughts!
