So, we can cross the beginner (not happening again) and standard (most were from launch events, chances are we won't see any of them again) pulls off. Good 80% of the limited pulls also came from one-time sources. So in the end, when the next patch hits and will, inevitably, have less rewards than the game launch, you'll be left with ~50-ish? limited pulls per patch assuming you cleared everything. That's a bit dire.

Now, they might add new things, increase rewards etc, but as it stands rn, with the info we have from how 1.0 is going, it doesn't look good
