Oh wow...they look cool and it looks like there is one for each subclass. I finished one already. Luckily it wasn't too bad with friends (Voidwalker). It may still be unlocked on 9/15 because subclasses were not included in the Help post. Not to mention we finished these subclasses in year one. But I'm not going to complete anymore. Just get to the last step and turn them in on Tuesday.
