Blizzard's upcoming hero shooter Overwatch has had a lengthy run in closed beta, and core features are still being changed.
The latest modification is a new character progression system, replacing the developer's two prior attempts at creating one.
According to game director Jeff Kaplan, that system was ":super powerful and broken and unbalanced," so it was replaced with a system that unlocked cosmetic items as characters levelled up.
But even that system "[encouraged] the wrong behaviour," making players stick to a single character instead of switching amongst multiple heroes.
Kaplan says the new progression system is "light, cosmetic and almost [like] the game thanking you for your time in it," with little bearing on gameplay.
The system will debut in Overwatch's next round of closed beta testing in mid-January.
Overwatch is due for release on new-gen consoles and PC by the end of June 2016.
