Shitter here, I'm almost to the point where I'll be able to clear 2-1 for the first time. I need some new ships, particularly Heavy Cruisers so I can unlock quest A12 and get my third fleet, but also something to replace my destroyers for regular farming - they're basically dead weight when none of the battles make it to the torpedo phase and my carriers/battleship all oneshot most enemies. However, I also know that 1-5 is a key farming map and requires a very specific equipment set. At this point in the game, what would be a better option for me: grinding 2-1 for ships that will better help me progress through the rest of world 2, or spending more resources trying to develop anti-sub weapons to get me to reliably clear 1-5?

Pic related is my team, I've only been playing for two days so while I am following along with the pastebin list of good ships to keep I'm mostly just taking what I'm given in terms of drops
