You both are correctish, moreso point09.

E4AE is regardless beneficial as they is no CD debuff
But virus I would argue isnt that great on blm due to a few things
-most mass AOEs e.g gigaflare, nerve gas, hellfire etc are magic damage and the BLM virus does nothing to this.
-Also while it does help with STR debuffing most BLMs use it at the wrong times which means antivirus is up when a SMN/SCH need to debuff properly. It's useful but not amazing.



But when discussing jobs you need to make it job specific, no point me saying CNJ is better than WHM because its 9 utilites which are half useful y'know.

BLM:
manaward - very meh only reduces damage by negligible amount, by comparison second wind destroys it and it is only applied to the BLM so not a party utility.
Manawall - alot better then manaward as you can use it for earthshockers etc but same as above helpful but any other dps can deal with the mechanics with heals or good timing e.g. titan LB on adds etc
apoc - amazing utility and should be used more often.
Lethargy - works on little where it matters usually overshadowed by miasma
Freeze - same as above shadowed by tri disaster, plus it will mess up fire/ice rotation where you should only have time to apply thunder then be back on fire so very rarely viable.
Sleep - amazing utility pvp, speedruns, etc but end game useless.

SMN
Virus - raid wide damage reduction of all types of damage.
E4AE - same as above and can be triggered on limitless mobs while it is up.
Resurrection - while you shouldnt be doing it at all, with ballad it is very viable raid utility and something no other class can do. There is a reason skills like auto life, life, raise etc are fundamental in RPGs and the fact a dps can do it is great. However without someone dying it is as useful as zilch, so it is situation-reliant.
Miasma - see above, also if they bring out mobs who regen as a mechanic, not the when I eat I get full health nonsense it will be even better.
SF - very minimal not worth mentioning.
Stun - its a stun nothing more needed.
Blind - its a blind nothing more needed.
knock back- " "
DPS without having to target - on fights like levi, t5 etc the DOTs still tick when you are unable to target them.
Tri - Disaster - the more useful of the useless binds
