Danah's gameplay is extremely simplistic. She has a low skill floor and a low skill ceiling. There is little room to min-max damage output. She was like the last character to even get a guide written for her (was there even one written for her?) during the community event to write guides for each character.
Her SP moves just sort of exist in a isolation and little interaction with 3 of them performing the same function: damage and mana generation.
Suggestions:
Block should generate SP.
Active: Penitent Slash cooldown should be reduced from 20 seconds to 15 seconds.
Active: Mourning should be able to be charged for more damage and mana generation like Lann's Raging Fever.
Active: Purify Evil is only used to restore stamina, which is not that common since Danah doesnt have bad stamina management anymore. This ability should provide an attack speed buff for 30 seconds.
Active: Ritual Ending should have its cooldown reduced for every successful final attack in Danah's counterattack ability.
Thank you for attending my Ted talk, buff danah ty
raging fever can't be charged. he can charge GUST sting, which can then be chained into raging fever. an actual comparison would be the move grimden can charge (forgot it's name. i think 'cleave'?) or sanya's rmb. or sou's tab rmb
