Regardless, Heroes of the Storm are actually awesome. They force teamwork, as they should, and the variety of maps is awesome. The meta is not focused on laning so much, just follow the leader kind-of-thing. So that the entire team (other 4 players) don't have to suffer if a teammate is doing bad. There are some issues (Nova is broken currently) and the stealth mechanic is puzzling to the new players - basically, you see a premade going Tassadar/Nova combo and 1shotting almost any other hero. This is coming from a Diamond LoL player btw.
Ya, HotS is pretty fun. I'm really hoping the community jumps on map design like they did in BW/SC2 to the point to where community made maps were dominant. I think the community could come up with some insane maps to play on.
