I started around May (Sadly missing to get Gangut :( ). I only go to 1-5 to get the medal and ignore it afterwards.
I guess I'll start training my CAs (Mainly Maya, Choukai, Kako, and Furutaka) and sadly my only CVLs are Houshou and Hiyou. I'm about lvl 58 (will get to 60+ by the event) and I'm busy stockpiling resources and buckets (280+) since it's advised to start hardcapping.
Lastly, I'm poor as hell so I need to control my ship girl slots xP
