...True Name Discernment B maxes out at 30%. Jeanne's NP is typically what you're using to block enemy NPs. You'd need 70 more to actually negate an enemy NP, and NP damage reduction isn't that common, nor does anyone reduce it at a particularly high amount, except perhaps KoGil w/ Overcharge, which still requires 300% charge to get to 70% NP reduc.

Without that much charge on KoGil, you're leaving the enemy w/ 10 or 20% NP damage left, which, while tolerable on most AoE NPs, ST NPs from stronger enemies might still be able to kill. Also of note is that True Name Revelation only affects a singular servant enemy, which makes this set up even more situational if you're fighting multiple or non-servant enemies.

Granted, there are some cases where enemy NP pierces invulnerability, but in those cases, it's typically better to raise defense to 100% with set ups using Mashu, or reduce enemy Attack to 0% with set ups using Asterios.
