I really loved hots until hgc ended. It's my personal favourite and i tried Dota 2, Smite and LoL (Lol Gold/Plat) as well. Heroes of the Storm is fascinating because the fights are not instantly over as in LoL and Dota and you don't have to be 100% concentrated for each little detail as minion lasthits and too many depending items. I've got the best experienced with the community until season 3 (because now only idiots play that game and/or the space between noobs and gm players is waaay to wide) and it's really dependent on the team interactions (which I personally like because I've allways played with friends and coordinated via discord). It's all depending, if you like snowballing all alone or prefer teamplay. At the end I was around masters in Hots.
