Getting back into Helldivers 2 after 8 months, what to do?

I last played this game in April and I am now picking it back up again, or intend to, after seeing the update on the Game Awards and seeing it more often in my for-you pages and whatnot. When I did play, I only got up to Level 9. I only have 2 things unlocked on my destroyer. I'd like to start dicing up some calamari but I am hoping it won't be much of a grind. Is there a good warbond I could get? Specific upgrades? Please help me out, thanks
