"The rewards were so far out that they just gave up. So one of the things I was looking at doing was increasing the rate of reward, giving players more tangible goals to achieve in-between levels. But then it dawned on me, well if we did that, what’s the point of having levels at all?"
After a redesign, Firefall now has a tier-based system that doesn't limit players to a single class. Various branches can be levelled up, and if you become bored of your abilities, changes can be made quickly.
Firefall is yet to be given a release date, but should be released for PC in the not-so-distant future.
