Advice to comeback player

Hi team!

I want to return to the game, i left it at the last chapter of shadowbringers expansion, but what is happening to me is that i feel so underwealming with all the stuff i had that i dont remember, to all the combos of the classes to all the armor sets and the different systems and maps.
I really have been thinking of starting an alt but play all the base game again holds me back.

Do you guys have any advice on how to return to the game with the most organic way? or can i make an alt and skip the base game story?

Thanks for ur time and srry for my english, not my main lenguage ;)
