Honestly, as an i100 DRG in T9, I have no idea what you're talking about. Unshielded, Moggle's meteor never pushes me below 1700, meteors do 630 damage to me and 610 to everyone else, we have second wind, allagan field on me won't hurt anyone if I get just as much shielding as anyone else, and there are absolutely no conditions where this has any effect. I've read this whole thread going "what?" because I've absolutely never noticed this having any effect at all. A bigger problem is BLMs having as much Pdef as we have Mdef, but much less hp. Honestly, if this tiny effect is having such impact on your group, there's nothing to say about it other than you're a bad dragoon.
