This is not true at all with 6.3 and even 6.2 PLD. For 6.3 PLD rotation, it's impossible for a PLD to fail at proccing Divine Veil. And so old veil and new veil are functionally the same just that new veil removes the added complexity that old veil have. Even at 6.2 you just have to be mindful of your Requiescat window and plan your divine veil accordingly. For 6.2 PLD their physical filler rotation is either 37.5s or 45s long, since Divine Veil shield duration is 30 seconds there are only 7.5s or 15s dead period where you can't cover raidwides with divine veil. I can assure you that situation is actually extremely rare, and if that ever happens there are always another mechanic that damages the entire party before or right after that dead period. And the good thing about 6.3 PLD rotation is that it completely removed that dead period.
