Nice, I like this direction.
Agree on both fronts:
- Ballers should have the autonomy to allocate across both L1 and L2.
- T4 is a good idea, but a reduced number of slots seems better to manage (not too much overhead on analyzing candidate pools), as those slots could/should rotate faster than the ones from T2 and T3.
5 slots for T4 instead of 20 seems to be a good compromise.
