People have to stop seeing SCH and Sage as healers.
They're dps.
Sch is a chipdamage dps (the dots HURT A LOT, you just dont see it immediately). You can adlo people for damage buffs and spread your dots regardless of guards.
Sage is more of a burster with phlegma.
Whm and Sage are more healer, but they are also more support than straight up healers, too.
WHM has 3 chonky heals with 2 cures and one cure 3. LB gives a HoT, so its usually just gonna overheal and or not tick enough to save people (in a very close fight it might not help a lot). That is why whm usually has high healing power. Doesn't mean they actually HEALED a lot, they just have big range on their lb so everybody gets a HoT, aka overhealing.
Asts is a little more focused with 2 regens (normal benefic) and 2 shields (doublecast benefic) and Macrocosmos is a nice chunky heal if people can take care of themself a bit.
But people really hope to much that healers can always save them so they run around with a lot of mp next to me while i'm just waiting for any of my heals to be off cooldown.
Take care of yourself and i can take care of you.
No healer can keep you up if you can't weave in and out of danger and just GO.
SCH and sage would probably have more playrates (even if i see both a lot) if people would stop seeing them as healers and more as slight support but also just dps. GNB is also literally just a dps at this point.
It IS perfectly doable to win with no healer (no green) against teams that have healers (aka ast or whm) if the people don't just rush in and take a little care of themself. Because ONLY if you can take care of yourself, a healer can also help you better.
Sage and SCH just aren't healers and CAN put out an absurd amount of damage, the expectations that they ARE healers has to go away tho.
I play Ast and if i see a sage and SCH in my team, i don't expect them to heal a lot, because they can't. What i do expect them to do is play smart and do dps, because i see them as dps with some healing capability and don't rely on them to do some clutch healings (they can, but i can do it easier).
Green doesn't make a healer in PVP
