Updates include changes to skills and DNA, Season 1 and 2 items, EXP and lant drop increases among certain monsters/dungeons, battlefield updates, new quests, bug fixes and more. You can read the full list of patch notes on the official forums.
The changes to the skills and DNA seem to have come at an odd time, considering that the free skill respec items given to plays by Gravity were set to expire by this maintenance period. Players were told to ‘use it or lose it’, but now players are in a situation where they’ve respecced their characters only to have everything changed on them again. Except this time, there are no free respecs (yet).
