When I first started playing HOTS it was a bit addictive and I played far more than I should have. Especially when new heroes that I wanted to try were released, that would increase my average playtime.
With the reduced release of any new content and my dislike for Storm League, I don’t play all that frequently which I think is probably more healthy. The MOBA genre can be a bit stressful at times, it’s not a Diablo 3 like game where you can just relax and chill and press pause at anytime, well if you’re playing it solo at least.
