So, how about dat RDM Nerf? If Embolden really is a 6% rdps buff that's completely insane and offers 4 times as much rdps as the 1.7% TA, which on it's own already makes NIN a permanent melee. So long as Embolden exists in it's current form, no matter how much they buff BLM/SMN, they will be permanently locked out of all raid tiers.
*This is of course assuming that the above is correct.
