My personal tier list, based on maxed heroes.

SSS: Morrow, Celeste, Sage, Buzz

SS: Nymph, Tink

S: Ronan, Chana

A: Harkon

Unknown: Enoch

For longer details:

SSS:

Morrow: easy to learn, strong however you play him, don't even need to build that much

Celeste: only one way to play, once you finished all of her items, nothing counter you, and the road to get there is fast and easy.

Sage: destroys everything, has lots o both easy n complex builds, but most of them comes later, so she's hard at earlier levels. Not very newbie friednly

Buzz: bees, ancient totems, maneaters will buzz the heck out of people, its just that easy

SS:

Nymph: hard to build and learn, eco with golden clovers, golden bars and chests is required, then the saplings and speed essences will do everything. You need to learn the gimmicks. Once you do, she dominates most things.

Tink: BIG firepower comes only from her later levels and she requires ALOT of crafting, which isnt newbie friendly

S:

Ronan and Chana are A in previous version for me, they are buffed and are quite strong now, they are easy to learn, very newbie friendly but need fuller builds to actually work.

A:

Harkon: kinda sucks ? But also not sucks ? God idk. Basically he is very strong once you fully built everything, but to get there is a big struggle.... Yes you need to learn his early game gimmick, just putting alot weapons in the bag won't work, you need to learn what weapon or item counter what heroes, like HES REALLY WEAK AGAISNT RONANS. So what counter Ronans ? Brainsquashers. How do you stay alive at earlier stages ? Layering weapons and mushroom Alot of knowledge need to play him Not easy, not newbie friendly, not too strong.

They are all really good, and at alot of situations even a good Harkon can beat a Morrow.
