>Is it really optional if it gives so much stuff?
You have a few options
1. Autoselect and enter gluemas into Open league, maybe spend 1-2 careers doing that. Zero effort required.
2. Autoselect some random shitters and enter them into Graded league. Very likely to get to B finals (only need 1 win out of 40). Literally zero effort required if you do your "optional" daily career a day.
3. Sweat your balls off to get in A and maybe win. Only do this if that's fun to you.
The rewards REALLY aren't that different between the three of them. If you don't want to put in the effort, choose option 1 or 2. Is it really that hard...to just enter a fucking uma you lazy neigher?
