I didn't say the Potency increase didn't matter. I said you don't know what it is. But it will not be on the levels to make Black Mage's contributed raid dps competitive with other meta classes, especially given SAM's dps is being untouched.
Thundercloud change does not remove the problems of Thundercloud that is detailed in my thread and furthermore if you manage your procs correctly, you don't waste a proc in that way - only by having one overwrite a proc.
Transpose is 100% meaningless because you can already keep up Enochian 100%.
And leveling? That is irrelevant to the discussion of end game balance.
I understand the class to a decent level imo, but maybe you should play it in Savage level content someday to be commenting on it.
If there isn't a break in the fight, there is zero reason to use transpose in Savage/Ultimate level content. For AOE, at end game, it makes no difference, you do the same rotation.
AM timer is meaningless, i've never had to use it that often and Susano Ex jumping is already mitigated by stutterstepping, triplecast, sharpcast, swiftcast and procs. Movement is not an issue for BLM.
Fire proc changes make 0 difference whatsoever. You should never lose a firestarter proc if you play correctly. Thundercloud procs - near meaningless because the main time you lose procs is from procs being overwritten. The only change for this will be saving procs for Umbral Ice which you should do anyway if you get them in your second AF. As you said, they make the class easier to play but do nothing for the problem of the class - that its performance ceiling is poor compared to other classes.
Does SMN in 4.1 ring a bell?
I never said I expected complete overhauls. Hell, with SE's track record with BLM, I don't expect a thing as its clear they dislike the class.
But a potency buff that will not be above 20 potency is absolutely not enough. And some QoL changes would go a long way.
Maybe you should take a step back and look at how Black Mage has been treated for a long time. But don't worry, we'll either have 3 x Melee + 1 x Physical Ranged or 2 x Melee + 2 x Physical Ranged compositions. Again.
