everyone is whining it seems,Im guilty of it too.
I thought of my games and I can say a really high percentage of my losses are me making mistakes(from small one to massive brain freeze,roping out,wrong order plays,etc...) and this makes me feel way better than crying about rng.
Im sure Im one of the worst players in this forum,I have a low knowledge of decks and meta and I often quit the game for a month or 2 then comeback.
I dont practice decks and jump into ranked with any new deck and have no idea what im supposed to do.
And the worst part is Im playing so bad Im actually afraid rng was kind to me till now
ps:I dont even know all the game mechanics and some cards I encounter I have literally never heard of them before.
