League of Legends aims for harmony with new Team Builder feature
Essentially, the Team Builder allows players to designate their preferred playstyle and strategy, and then the system attempts to match up those with similar mindsets. This saves players the trouble of wondering who's going to play which role, who will be in which lane, and what the team's overall strategy will be, hopefully resulting in a much more harmonious gameplay experience. On top of that, the Team Builder will also include a "smarter matchmaking system that can dynamically account for your experience with a given role, position or champion," so players looking to change up their playstyle need not be afraid of invoking the ire of their teammates as they learn. For all the nitty gritty details on the Team Builder, check out the full post over at the League of Legends forums.
