Duel Links is sucks because:
1. The skill system sucks, it ruins the balance of the game.
2. Cards are expensive and hard to obtain. Even R rarity in structure decks will need to pay $ to obtain.
3. The banlist system is different from traditional YGO (TCG/OCG). There are global limited 1, 2, and 3. For example, in TCG/OCG you can use all limited 1 cards, 1 copy each in your deck. But in DL, you can only put 1 copy of limited 1 cards from all the listed, and only that card.
4. Game design sucks. Gold is kinda useless for old timers. I have 5 million gold but it is does not matter because of how useless it is.

If you like YGO, play Master Duel Instead. Master duel is cheaper and more balanced.

Died a long time ago ;(
