Yes, there will be some wailing and gnashing of teeth, but the announcement explicitly outlines the reasons why the mechanics and features like the menagerie won’t be sticking around. In short, as much as the team (and players) enjoyed parts of the Bestiary experience, it’d create problems for new players and for keeping the menagerie updated, while demanding even more work to keep the crafting balanced. So it’s sad news if you had really hoped to keep the Bestiary League around in some form, but it seems like the best long-term health decision… even if it’ll be hard for the next league to be half as well-loved.
Path of Exile players like the game’s Bestiary League. It’s been a real breakout success for the game, and the combination of the game’s core mechanics with the promise of capturing rare beasts (and using them for armor) has delighted many fans. So it’s a good thing to read that the game will most definitely be getting rid of the bestiary league mechanics following the end of the league cycle.
