I never asked for A, tbh I think that's to much anyways. B is what we have in Sword, Dagger, and Enhancing Magic, the only skill RDM has above a B rank is Enfeebling. B is 404 which excluding gear is a nice 20 behind a PLD, roughly 5% block rate from what I understand. C+ would be fine too, it's not to much lower and is another common skill we have.

The set sounds right, I would have to go look and fix my sets for melee on FFXIAH to suggest any improvements if there are any to be made but it's fine to me. I won't like that in optimum gear a RDM can get capped PDT somewhat easily, but comparing it to PLD isn't even close. PLD Relic Head, Body, and Legs alone amount to 3 of the highest DEF pieces if not the highest DEF piece in slot in the game on top of a total of 20% PDT between them. I don't mean to say RDM has a hard time getting PDT, but more that PLD has an insanely easy time getting it by compare to any other job, and with the ability to stack on so much PDT and their JAs it really makes PLD hard to beat.

PLD at 75 was competing with RDM but it was a different game back then, at the time Aegis was rare, now every PLD and their mom has one, back then your block rate was your block rate, now days PLD has 2 abilities to raise that rate sky high and one of them can be full timed with proper buffs/gear. I don't mean RDM would be too weak to make use of this, but to out do a PLD would be near impossible at this point unless you're talking about a maxed out RDM vs a half assed PLD, in which case I think the argument against raising the skill to high is a bit unfair.
