Last Halloween, the Lunatic Court followed through on an ill-conceived plot to free Mad King Thorn from his realm. Seals were broken, bizarre acts were performed, terrible jokes were deciphered, and it seemed at the time that all the fuss had been for nothing.
But since then, instability has begun to seep into the world, gathering in the places where the influence of the Mists is felt most strongly. The instability has resulted in fluctuations – changes that alter the experience of playing in our competitive venues. Fluctuations seem to come and go, bringing new effects with them every month.
The introduction of Flux is a compelling tool to help us keep our competitive formats dynamic, while allowing us to further balance the game. Because slight shifts in the meta are expected from Flux to Flux, it allows us to better target overly problematic builds. If powerful builds can thrive in environments that are not suited to them, we can review the skills to bring them more into line. We want to encourage gameplay where the team that wins does so because they've played more skillfully.
The Flux system is the precursor to several improvements that will be coming in a PvP-specific update. We'll be taking a look at improving some titles, the incentives to play, the rewards for various formats, and more. Look forward to it!
Flux is an environment effect present in Player versus Player areas that changes on the first of every month (UTC). Flux affects player characters and does not affect NPCs. It also affects heroes in the Isle of the Nameless (PvP) and Training Arena.
