I think SE realized the issue they had in XI, by creating a DPS job with no inherent weaknesses (other than fragile hp and defense), the single most used (hell, the only one available) crowd control spell in the game, and giving them a way to counteract any defense possible (other than flat magical damage reduction). The glory days of BLM will never come again. Now, they can be powerful and fun to play (and I hope they do become that for you).... but if your sense of fun is having a class with very little weakness, then you're barking up the wrong tree. No MMO can afford to alienate the player base by having any "God-Tier" jobs. Look at SWTOR with consulars/inquisitors, they went months without any meaningful adjustments... I'm almost positive seeing such a staggering class imbalance played a small part in their sub numbers dropping.

Now, if you were to propose each class/job getting a unique form of single target CC (useful as sleepga or more due to it being single target), meaningful debuffs (that don't have to be part of a 3rd rate combo chain), and improved group utility, I could get behind the idea of BLM buffs in addition to that. But you didn't, you're asking for all the cookies in the jar and leaving the other classes with crumbs.

SE hopefully realizes the mistake they made by using monster physical defense as an artificial gateway to content (in XI), yet magic defense on monsters was nearly non existent (HNM's excluded obviously). Right now they're in a good spot (if HM Darnus and post-fix Garuda are any indication) where you'll need both magic and physical damage to handle content.
