I don't know about that, RDMs can reach the magic-50% cap easily and still add some MDB gear, and on top of that they have an innate +12 MDB from their traits. Furthermore we have Stoneskin that cuts any Magical Damage we take by a lot. Only fights I can think of I can't keep Stoneskin always up are Dark Ixion, Byakko and Jailer of Prudence.

And even when Stoneskin isn't up cause, for instance, Cerb is particularly GoH-Happy, this is what the damage looks like

You can use a phys- set whenever its needed. I'm personally able to switch into it whenever I'm going to get hit by things like Tourbillion, Rampart Stance, etc, and of course, normal hits.Damage reduction gear is only useful if you can anticipate nasty attacks/TP moves, most of the time they are only used in "ohshit" macro as the last resort to keep RDM alive. Have you ever wondered why PLD don't carry Darksteel set?
??The most important function of stoneskin is to prevent spell interruption when RDM try to get shadow back up. Many touch HNMs in this game will shred through stoneskin and deciminate your tank in seconds when both utsusemi are down.Sentinel/reprisal/shield block give PLD much bigger error margin when things go wrong.
Even when Fulmination goes off, I'm hard to "decimate"

I will love to see your RDM/NIN solo tank Cerberus.Spoiler: show

I love my Cure stal macro especially on Dark Ixion, where you dont have the time to spam Blind/Bind for VE while keeping shadows up and running away from TP moves. I also always cure DDs during Sandworm fights and Cerb, MP is hardly ever an issue and stal makes it very easy to do so.The only person RDM tank should cast cure on is the RDM him/herself or the co-tank. The same amount of MP can be used to cast more low cost hate spells plus attempt to locate players who are not in your party will only slow yourself down. If your DDs keep taking damage may be it's time for them to learn how to back off and stay out of aoe/spell range.
As for whether it's possible to solo tank DI as RDM, it's very possible, and you can also keep CE/VE both capped with some experience. I solo tank Ixion for my LS all the times and our kill times are between 25mins (full ally) and 60mins (9-10 ppl).

Sorry for the large number of pictures but I wanted to avoid the "poidh" crap
