Well if we're focusing on what ifs, I'd prefer RDM not become a cheap one-trick pony just because the players are desperate to attend events. Improving enfeebling is as important for RDM as it is for any job that enfeebles (not counting Weapon Skill procs), but it's important to remember the type of mobs we have trouble on have always been troublesome. Enfeebling has been kind of a non-entity against bosses in every FF game. If it wasn't, the bosses wouldn't be worth their title. Indeed, has a little more potential than to just hide in the backline when fighting event bosses.

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.

Finally, would it really be so blasphemous to share Regen 3 and Reraise with us? One is a self-cast spell that steps on no one's toes, the other would be so late-game (because of the level they introduced Regen 2), that it simply doesn't pose a threat to the other jobs that utilize it.
