Guild Wars 2 is not planning to neglect its fractal content when Heart of Thorns comes out later this year. The fantasy MMO put up a dev blog today discussing how the team is simultaneously making the scaling group content easier to access and more challenging.
One big change with the expansion is that players will be able to choose a specific fractal to run from a list instead of a grouping of randomized dungeons. This will allow for shorter runs and players to get to learn certain fractals better. Another change is that fractals are going to scale up to 100, offering a harder difficulty level for seasoned groups. There will also be plenty of new rewards and achievements for running fractals, in case you needed incentive.
ArenaNet also outlined how it will be giving players a path to earning a legendary backpack in the expansion: “Just like existing legendary items, players will need to collect components from all over Tyria. To craft each stage of the precursor backpack, players will need to obtain a new salvage item from ascended equipment.”
