i used to play bdo 2-3 years ago, i have a maehwa lvl 60 243 ap

i'm returning to this game now and i will create a new season char to get the bosses equip faster, so here is my question, i don't know which class to choose for my new char, so which class? i really like maehwa's mobility so, there is any class like her in game? wu-sa really interested me but i don't know if she haves high mobility and all

Woosa is an option but her long range mobility is more complex than maewha. You can still try her, she has a lot of movement as well.

Other options would be Drakania (especially awakening), Musa (since he is the same as maewha but male), Maegu (similar movement to Woosa), Nova Awakening (more bursty than maewha but also fast movement) and Lahn (her movement is a bit different, but still has a lot of it)

You know it depens on how much "better" a class shall be or if you want to play because it's fun...
Because BDO still sucks hard for balance.
And all the new classes are better than the old ones except for a few (like Succ Witch for example)
You will have disadvantage if playing something like Tamer, Kunoichi, Musa/Meahwa, DK and else compared if you want max grindspeed.
Guess why you rarely see some of them but tons of Guardians, Woosa and Lahn...
