It's almost 2 years since I stopped playing the game. I was 75 in all classes and the new 12* and 13* stuff was the hottest. Episode 4 was just launched and Fo was the most op class.

I logged today and I felt more lost than the day I started playing.

I used to play Br/Hu when Average Stance was still a thing. I also mained Ra/Br with that insane dmg to weakpoints. Now all that has changed.

So, what should I be looking for to come back as a decent player? I know there's a new Hero class, and a lot new 13* and 14* stuff, also rings.
Is Br/Hu katana still viable? what about Gu? Most important quest to do these days?
I have so many questions... xD But I guess is best to start playing and see for myself :S
