Why basic sage damage skill have 300 potency and astro or scholar have only 150

[Kenarashi]

So as a sage I have tons of damage skills but as a astro my basic skill does damage of 150 instead of 300 like sage. Also sage has couple more abilities that does damage as a astro i don't. It is really a pain when i try to solo older content or Fates etc as astro. At least white mages have blood lily.

As a sage you do not have tons of damage skills. you got the same as the rest that isn't astro

1 nuke (dosis) vs glare, malefic and broil
1 dot (also dosis) vs dia, combust and biolysis
1 aoe (dykrasia) vs holy, gravity and slap of war
1 extra (plegma balls) vs assize, (astro not found) energy drain

whm has a gcd refund as you say- misery.
Ast has macrocosmos and earthly star that are used for their healing power that happen to deal damage
sage has pneuma that again is used as a healing tool that happens to deal damage and toxikon which is used anywhere from 0-3 times a fight. more if there's invincibility period on the boss

astros crown card play would be the 1 extra, if it comes up Lord at least

By a ton you mean 2? One of which is a 45s CD

AST has its cards and Astrodyne to compensate for the lower potency on its spammable offensive abilities.

Also, the job guide for SGE is wrong and it does NOT have 300 potency on Dosis when scaled down. It starts off at 180, upgrades to 250 at level 54, then only is 300 at level 64.

dosis lvl 1 300 potency dosis II 320 potency lvl 72 dosis III 330 potency

[Seraphor]

dosis lvl 1 300 potency dosis II 320 potency lvl 72 dosis III 330 potency

Dosis starts at 180 and is increased via traits:

Somanoutic Oath
Lv. 54 Increases the potency of Dosis to 250
Somanoutic Oath II
Lv. 64 Increases the potency of Dosis to 300
Then you get Dosis II and Dosis III.
Similar to how AST has Malefic I, II, III, IV and Fall Malefic, and SCH has Ruin, Broil, Broil II, III and IV, they all have 5 tiers.

It's already been explained that AST and SCH's damage buffs make up for their lower potencies. This has to be balanced around 8-man content. So yeah, SCH and especially AST are going to be less powerful in solo content because they can't bolster their damage output with 7 other plays increased damage, it kinda sucks but its not a huge deal, the fights take a little bit longer, but they're both healers so you're not going to die.

[Silver-Strider]

It's because of how the game is balanced.
AST and SCH have utility that helps groups do more damage, making up for their lack of personal damage.
SGE and WHM don't have utility and only bring their personal damage to the table so they have higher potency on their attacks.

It kind of handicaps AST and SCH in terms of Solo play though because their utility doesn't make their own damage that much better and just makes things take longer to complete as a result.

SGE’s higher potency is because it does not offer party utility the way AST does. AST has lower potency because a lot of its overall damage comes from the buffs it gives the party in the form of its cards and Divination. Generally speaking, “selfish” jobs in this game (i.e., jobs that do not have party buffs) have higher skill potencies than “buff” jobs (i.e., jobs that have party buffs).

The “extras” in SGE’s kit don’t really set it apart much from the other healers. All four have the same basic and boring formula of 1 DoT, 1 nuke, and 1 AOE. Only some have these “extra” abilities, and they don’t really add any extra “umpf” to any of them.

Phlegma is just WHM’s Assize, except without a heal and MP regen attached. It’s actually a bit better due to having 2 charges, but it’s functionally the same: most of the time, it is used on cooldown.

Toxikon is a more limited version of SCH’s Ruin II—it’s used primarily for movement and not regularly due to 1. How it is generated, and 2. It’s the same potency as Dosis, so there’s no damage gain from using Toxikon over Dosis. It’s DPS neutral to generate during downtime and a DPS loss to generate when enemies are targetable.

Pneuma is used primarily for its heal, not for its damage. The potency is the same as Dosis, and the cooldown is 2 minutes. It’s similar to Macrocosmos except without the damage taken : healing received scale factor and with a shorter cooldown. Pneuma does require an enemy target to use versus Macro, which does not.

WHM has Misery as a refund from casting 3 GCD heals via Solace or Rapture. The other healers don’t have to GCD heal as often as WHM does since their kits contain so many oGCD healing abilities, versus WHM’s which does not. Hence why Misery exists. And now, it’s not a DPS loss to generate it: it’s a full refund for the three GCD spent to generate it.
