BLM needs more damage

Permanent vulnerabilities should belong to the tanks, not DPS.

Actually, the slashing vulnerability is now fairly balanced across the jobs that bring it. When WAR was the only job that could apply it without losing damage the balancement was way worse. The issue of Piercing debuff is that only one job can provide it while 3 jobs deal piercing damage as their main output. RDM ogcds are all piercing too, being a 4th job able to deal piercing damage. Blunt damage debuff only does not causes issues because aside from some DoM's auto attacks, no other job does blunt.
