NS are pretty OP. And to make Talzin a 2 year farm was just silly. They realized that and have adjusted the cadence accordingly. This decision makes perfect sense for the vast majority of the player base.
The only people complaining are those that spent a lot of money to level up Talzin, so that they could have an advantage over others. Well, you had that advantage for months. But you had to know there was a chance she would be farmable before 2 years went by. Come on. Be realistic.
