I gave it a try on Saturday and the game is rather fun. You're looking at 20 minute matches when playing against others Sledge (in the normal mode, haven't tried it but friends of mine who play it say that's how long a normal match lasts), Brawl is roughly 10 minute matches (which is what I played, it's fucking fun as hell). If I had to assume I would guess, depending on how hard you set the A.I., you'd be looking at 10-20 minute matches (and whether you do it alone or with others). The thing about HotS is that everything is completely balanced unlike in other MOBA's. There are no weapons/trinkets/armor to buy (making it so there are no builds you need to go for) and everyone levels at the same time as long as NPC's/Heroes are being killed. Each character has talents that you choose from every few levels to help distinguish your build (kind of like how Battleborn was setup) from other Heroes. Honestly, as much as I love the original DOTA and Smite, this game is extremely fun, easy to get into, and extremely forgiving (I ignore party chat for the most part but from what I saw it's a lot tamer then Smite chat (which is downright toxic)). I'm suggest giving it a shot but then again MOBA's aren't for everyone (and for me the game is so much more fun then slogging through Quickmatch Overwatch, I still want to buy the game but I just don't want to slog through Quickmatch to get to 25 so I can play comp).
