It seems they've focused magic tanking on RNF, but it would be nice to see RDM's self-buffing capabilities juiced up. Maybe leaving out the hate-holding abilities of the more specialized tanks, but something that reminds everyone the job isn't as soft as some of the specialist classes. We get Phalanx, Stoneskin, Protect, Shell, and a full range of Bar-spells. It might be nice to see maybe a JA adding HP to Stoneskin or damage reduction to Phalanx (at the cost of recast time, maybe). Perhaps another tier of these, for the Bar-spells as well. I don't know the reasons for not having Barlight and Bardark, but those might not be bad to have as well, in addition to Bar-statuses that we haven't already been given. The devs don't have to focus on tanking, but RDM has
way too many survival tools not to be further explored; if RNF is meant to be the first choice in magical tanking, it can't hurt to employ RDM as a second.
