I wonder why people hate them. Their decks are based on archtypes and they all have a unique strategy. Also, they got awesome cards. And GX's plot was better than DM... I don't know if you do watch Yugioh the Abridged Series but if you watch it you will realize that the plot was bad... Full of cliches and duels were not good. And if you insist that GX will ruin Duel Links, then just shut the up and delete the game.
I'd argue that saying, "And if you insist that GX will ruin Duel Links, then just shut the up and delete the game." weakens his argument and makes him sound like a 14 year old who just found out what Twitter is
They're likely still doing Gen 1 characters, though. They already hinted at a Bonz event in October, for example. And honestly, there isn't much left anyway. Just a bunch of filler arc characters and a few one-and-done characters that hardly had any screen time.
