The Repopulation comes ever closer to release with a larger pool of testers on both weekends and a regular basis. It also means that more big changes have been rolled out to the game, starting with Ability Enhancements. These slotted tricks fit into abilities similar to item fittings, with a variety of different enhancements available to improve a character's skills. The enhancement slots are limited, however, which forces players to think about how they want to specialize their characters.
Combat has also received a major tuning tweak, with a new off-hand option for those who'd prefer not to dual-wield melee weapons and a number of improved abilities. The refined combat system includes new openings and counter-attack support, which makes the system play nicer in a group setting. You can see the full patch notes and read more details on the official site.
