I can totally understand you. Ttar made this game look easy, but then I jumped in, max-leveling and everything, and still got smoked by the early game bosses multiple times. Same thing with Insurgence even. I was pretty jealous too ngl, trying to rationalize it (oh he got lucky, if this hadn't happened he would have lost, he overleveled that one Pokemon, etc.) Those totem battles prepared him for this.
I was jealous but never hated on him tho. How could anyone not love that face?!
