This is a match between two pro teams NaVi and Team Kick playing on Sky Temple during the Monthly Final of the Go4Heroes Tournament. It was shared by eSports veteran Khaldor. And it's intense.
NaVi's early game pressure is awesome and full of close calls. But it gets really ugly later on with a lot of 4v4 and 5v5 encounters (Arthas' "Sindragosa" ability always looks so cool in these encounters). Sky Temple is a map where teams have to capture temples that awaken periodically and hold them, because they will do the dirty work on the enemy team's forts.
Here's the full match with Khaldor's passionate commentary. Both teams are all over the place:
Seems like Heroes of the Storm is shaping up nicely and it looks just as fast and insane as League of Legends and DOTA 2 when it's played by pros.
