Unblockable attacks probably shouldn’t trigger proximity blocking… since you can’t block them. Here’s some examples (I actually checked every move):
- Argagarg poison fish [B]
- Jaina level 3 arrow [B]
- Setsuki teleport throw [C]
- Valerie back dash BB4B / A4B / AA4B
- Dragon T / 4T
- and I guess Lum fireworks on the way up
- and Lum cloud has proximity blocking even if you surpassed it
Also, a bit unrelated, but sometimes this happens to the opponent when he tries to block a mistimed meaty projectile:
