My favourite thing they’ve put in has to be their Guide system.
Since the launch of DOTA 2, they’ve made the tutorial more comprehensive by adding a last hit/deny practice tool, in-built bot games and, most importantly, playing a specific game mode against other players which feels like a safe place free from newbie ridicule. In general, it’s nice to know how to actually play the game you want to play. I started playing with a few friends, got drunk, had some laughs, put on some sensual music… I’m in a deeply committed relationship with this game and I’m going to tell you why I went from a some-time League of Legends player to a “I play DOTA 2 as my main game” player at record speed. As many of you may (or may not) remember, I wrote an article two years ago about why I didn’t want to play DOTA 2 which promptly turned into why I would never play DOTA 2 thanks to the kind, loving words of the community in the comments section.
