Well if this outburst happened after playing the game from its release I could understand the burn out from it, all the shit that happens in this game. It is time to take a break. Games should bring fun but with HS it is sometimes so frustrating to have fun when there are netdecking, emoting community and clueless devs (or intentional).
If your outbursts are happening often and are really snap ones, not building gradually you could maybe ask someone for help, that is where problem could really start.
I get angry at this game and community too, but not because losing, but getting totally destroyed by solitaire decks with no fun inbetween and netdecking players. But i do not destroy things lol, I just get really salty and turn off the game lol.
