This and also no -AGA nuke, and no -AGA sleep (beside Manifestation, which double cast time / cooldown... and /blm sleepga 1).
This mean SCH is unable to :
-Be efficient when
heavy crowd control is needed (like Dynamis, especially dreamland/tav).
-AGA manaburn :
>> xNM or quests (DM etc...), BLM AGA 3 will always be superior when it comes to this.
>>Salvage, in some situation like AR last floor, if a fanatic drink was available mid-run, BLM can grab it and Manafont+Fanatic drink. Can take down 6~7 gear alone which enable the party to clear the floor easily under 7 minutes. (can do <4min easy).
>>Lesser mobs / PH killing, BLM can train 10+ small mobs like Eft or Bugards and take these down with a couple of AGA III spells.
>>Ix'Aern DRG spawn, can AGA III all aerns and clear the room really fast.
>>Dynamis Xar, killing all eyes with AGA III. Ying/Yang with AGA III also.
-Timenuke in general, what matters only is the damage spike, you don't care about dmg/MP efficiency.
-Get the +25 MaCC / +15% potency (+20% with AFv2 hands) bonus BLMs can get while MB'ing with AM II.
So yeah even if on long HNM fight SCH is more efficient than a blm (speaking about dmg/MP ratio here), I want say who cares about HNMs ? Ever saw a LS wiping because their BLM were out of MP ? Any decent shell can take down all HNMs nowadays anyway...
Now try doing Dynamis without a single BLM, have fun, especially in tavnazia, it's lovely. Clear xNM under 2min with some SCH. Enjoy your DM with a SCH burn etc... In most of event now, dmg/MP efficiency ain't that important,
Take Salvage for example :
-MP refill everyone floor, meaning often...
-Lot of MP restorative items, especially in SSR where it's items fest.
-
11MP/tick refresh (3 (RDM) + 2 (Ballad 1 with fife) + 3 (Ballad 2 with fife) + 1 (Sanction) + 1 (Body) + 1 (ToAU ring)). When BRD Sould Voice I barely see my MP going down. Even boss fight ain't an issue.
Who needs dmg/MP efficiency with this :/
Dynamis ? Lot of MP stats, double dark meaning good blm can aspir 130MP+ per 60 seconds in average.
Limbus ? Well BLM solo some area pretty well, nothing to add.
Assault ? Did all 50 with my BLM, no issue. Worse case, can always use an hi-elixir for emergency.
Soloing XP ? Well I can reach chain #6 on pudding camp with a BLM. I doubt SCH can reach chain #7. So at best it'll tie a BLM.

And no I'm not saying SCH is useless, SCH is a great job and very versatile. Still got many advantage over BLM in
some situations but it's far from replacing BLM.
