Honkai Star Rail Roster

hsr-roster.md

I'm pretty sure my gear is holding me back, but I'm curious what reddit would focus on with the roster below. I'm not sure if it's worth more to have more at 70, or stay the course with leveling and focus on the newest releases and getting them to 80. I have only a day or two of farming to get the last of the mats for Kafka so I can 80 her on pull. I typically just purchase the $100 shard pouch per new banner, and that has served me well so far.

So my major questions:

1. How important is 70 vs 80?
2. Who would you level next? Feel free to include or not Kafka/Luka.
3. Who should I focus gearing?

My Roster is below by level, and further below that by name. Additionally here is a link with each my 70 and 80 level characters and gear. Images provided by Rails Express

Thanks in advance.
