We've seen a few questions on this since it went live so just to confirm - the reward track lasts for the duration of the promotion. There's no daily resets or anything.
Feels pretty bad if you're not one of the lucky ones who have 50m on their track... So some people's track is pointless
The track keeps going infinitely, so if are someone choosing to use higher volumes of keys on this, there may be more opportunities.
That said, what you mentioned is definitely part of the trial here. By seeing what's ahead of you, on top of the guaranteed Stars/Lamps/Proteans, you can see if the Rewards Track contains additional things you want.
In your case, you know it doesn't have something you feel is worth your keys - and that's part of why this is very much a trial to see how that feels as an experience.
Please do let us know any other feedback you have as you use it, as we're trying to capture everything we can to pass to the team.
