One of the bigger system-wide changes is an alteration to how conditions work. Freeze, Shock, and Chill are now meant to last for 60ms for every 1% of health damage inflicted, up to a maximum of 50% damage (or 3,000ms). The idea is to reward players for improving duration of conditions and normalize some changes, though it will prevent builds that use low-damage electrical area attacks to inflict Shock. Check out all the details in the official posting.
