You most likely will be doing on easy due to the restrictions with ship-locking and your lack of decent leveled ships.The lack in level is quite clear in some of your ship categories (CA & FBB). If situation arises that allows higher difficulty(i.e early maps E-1,E-2 etc) do give it a try if it is within your capabilities.
You are recommended to do your daily improvement consistently. In the situation that you wish to conserve screw usage the following are recommended; AP shell, T93 Sonar(possible to upgrade to T4), 35.6cm gun and daihatsu.
Alright then. The biggest difference of Easy and Medium difficulty is ship-locking. You have to have sufficient amount of ships for each category required by the maps. Clearing all maps on medium seems unlikely but worth trying. Perhaps, you can do easy-medium mix.
Your ships could use some improvement. My matrix here is to count how many ships have higher level than the threshold level (for most category). let's say the threshold level considered is 70.
DDE: you might consider level them for a few level until they can do open ASW attacks. ~30-35 will do.
DD: You have more than 10 usable ships. I think it is good enough.
CL, CAV: I think they are relatively OK.
CA: Hmm, this is quite worrying since you don't have many high level ships. Perhaps, you may consider train Myoukou and/or Nachi up to second remodel so that you'll also have the 20.3 (no. 2) guns.
CVL: They are decent but their level are a bit on the low side.
CV(B): You have quite few high level ships but relatively OK. (OMG That dupe Taihou)
(F)BB(V): same with carriers, you have quite few high level ships.
Others: we don't know if the devs want us to use some 'others' ships to do routing. however, your ships in this category are not strong.
Resources:
You have to stock more to safely clearing the event. We don't know how much actually needed to clearing this upcoming event. it depends on the upcoming maps and your play style. It would be nice to have a minimum of ~70k for bauxite and ~100k for everything else. (you'll need more if you farm). For buckets, 700 would be sufficient(?) maybe.
Since the event is quite near, I suggest you stock up and hope for the best. Although, you can level some ship up but levelling cost resources and presumably buckets.
you have big problems with ca, none myoukou sisters k2, no maya k2 and no ducks. while you have cav all of them are weak. fbb too low lvled and just 1 k2 bongou
