Indie MMO Project Gorgon is currently trying out a couple of prototype ideas on the test server to see if they might be useful in the game proper.
The biggest change is a sweeping overhaul of the power system. In the test build, power no longer regenerates in combat while basic attacks are free to use and restore a small amount of power every 10 seconds when triggered.
In addition to experimenting with the power system, the team has buffed up monsters on the test server as well. Mobs now have more health and armor in order to extend combat length, which the devs have previously noted was too short.
