A defining characteristic of Heroes of the Storm the developer Blizzard loves to highlight is the fact that average match lengths are much shorter than those in Dota 2 and League of Legends. While that's still the case, data compiled by dedicated fans suggests HOTS game times are gradually increasing.
Using data drawn from the influential fan site Hotslogs, Heroes player and Reddit user yutinxiang found that average game length has been steadily creeping up over the course of the summer. With the exception of the two smallest maps in HOTS (which understandably produce the shortest matches), most games compiled now run over twenty minutes:
Previously, Blizzard has told Kotaku and many other sources that the majority of Heroes of the Storm games run under 20 minutes.
Is this a hugely important shift? No, at least not yet. But Heroes of the Storm only left beta at the beginning of the summer. If game length continues to climb the way it has since its official launch, the developer will likely need to account for it in some way -- if it wants to maintain its reputation at the quick-and-easy MOBA.
