The final rank-up was hard-blocked by a milestone gate nothing could ever satisfy. The gate is gone, and tier 4 to 5 is reachable again.

The XP ladder was re-sliced to match what the game actually awards, and tiers 3-5 carry an experience requirement once more, so a rank is something you accumulate toward as well as qualify for. A character sitting at a full sublevel bar keeps the bar full, even where the new ladder's threshold sits higher.

Completing a mission also no longer refills your Resonance and Stamina. A pool-max grant raises the ceiling and refills nothing; regeneration, rest, the Hospital and consumables are the ways to fill a pool back up.
