The diary makes it clear that while the number of people playing Forge is down, they believe a lot of that has to do with the steep learning curve new players experience. To fix this, there are plans for a new starter area in which players can practice against bots to get accustomed to the combat and the game mechanics. The team also plans to improve the tutorial and the UI so that what an ability does is more transparent.
For players already at the higher end, this is still good news -- the matchmaking system will be updated, visual customization will be improved, and you'll be able to respec at any time to ensure that you aren't stuck with poor choices forever. Check out all the details in the latest development diary.
