I got 3 characters to 30 over the network test just to unlock a few secondary passive options. Took about 8 hours each. Really not that bad and didn't feel grindy. This is one of the first games where I've genuinely enjoyed almost every character's kit.
These trophies dont seem too bad. But rank 100 on a character.....😅. Hopefully, they'll have some sort of exp character boost for the launch release or something.
