Yes, there are things all jobs can equip, but how anal are we going to be about maximization? As I can pretty much guarantee the "best" stuff won't be funneled off to melee RDMs. Hell, PLDs and BLUs likely wouldn't be a high priority, either.
For simplicity's sake, let's say they're all using the same waist (Warwolf), back (Cuch), rings (Strigoi/Rajas), earrings (Flame/Brutal), and a gorget. I get +22 STR, +15 DEX, +3 ATK, and +5 ACC before converting STR/DEX to their respective perks, too.
Now, if you wanted to pimp out STR, give them all Varingian Helm (+12) and Heafoc Mitts (+13). Not very likely, though. For head slots, PLDs can use Heca (+11) as an alternative. BLUs can use Aias Bonnet (+8). RDM's is reasonable alternative is Gnadbhod (+6), with Maat's Cap (+7) for the hardcore (which we know you're not), and Voyager Sallet (+4) for the average. The poor PLD will always have Perle (+5). Some of these have other mods like DEX, ATK, or ACC, but hey, I'll play your game and call ACC a wash. Overall, I'd say PLD's the winner in the head slot.
Moving on to bodies. RDM's STR options here are miserable. It's Nara/Vishnu only for +3/4 respectively. BLU has Aurore (+4), Enkidu (+5), AF(+1) (+3/5), Mirke (+5), and Nara/Vishnu again. In comes PLD to kick ass again. I won't list them all, but plenty have +5, Perle is +8, some have +11 and +12, Grim is +15/16. Only thing an average PLD may lose out on is a BLU who augmented Mirke with +10 ATK/ACC.
Hands are a fair fight with Heafoc ruled out. All three can use Alky's for +11.
STR in the leg slot doesn't see too many options for both RDM and BLU. Even for PLD, it's more likely they'll use it to shore up ACC. All 3 jobs can use some subligar with +8 STR, but they carry -10 ACC. PLD pulls ahead with options having both STR/ACC with Bahram Cuisses (5/12) while BLU's brother would be their AF3 pants (+8 STR) and their relic pants their little brother (3 STR/5 ACC). RDM? Well, you could use Dusk for ATK, Oily for ACC, or maybe you could've modified ASA pants with ACC, which isn't a shabby idea paired with the Haste option.
Feet for BLU has a number of +3/4 options. RDM's best is +3. PLD gets +5 from Perle as the poor man's. Clout boasts +9. Heca has +6 and they also have numerous +3 options.
Now, I dunno about you, but I see a lot of situations where you "average" RDM is gonna be in last place here against average others. As gear improves, PLDs pull further ahead on physical WS. RDM's physical WS options above don't exactly boast much DEX to help with Vorpal's crit rate if you're even subbed to use it while Perle/Heca carries that in modest amounts and BLUs can get their own share via Enkidu, Aurore, and others.
My claim is that physical WS don't exactly play to our strengths as healthy balances of stats are more difficult for us to achieve. We've seen Zaf talk about CDC and saying it's better than DB. That's cool. I don't doubt that. I'm glad, even. However, until he fiddles with gear (most likely DEX heavy) to see how it may differ to the set up I know he has, it stands to reason that PLD and BLU will outperform us on physical WS that aren't otherwise quirky. I know he's trying to get Razed Ruin Atma, too, which is a good move and something I've been trying to push my LS toward, as well.
If you wanna over-dramaticize my choice of "suffer" as a word to compare our gear to others, by all means keep doing so. All those little stats we don't get add up, though, and is more than enough fuel to get the parser crowd chirping while others just continue the blanket assertion that RDM melee offers nothing. If anything, consider my word choice an unspoken desire for better gear for us... which isn't a new request on my end, either.
