Finish E3 Hard yesterday
First boss and unlock, no big issue, however, difficulties come at second boss
This is the fleet that i used for final kill:

LBAS: 1 green 3 bombers for both LBAS all aim boss
I was trying to not use the nelson when i start the 2nd boss, however never finish the boss even once, just slowly reduce the red bar until final kill...
now a bit regret using nelson however no point of think about it since she already have the tag
before final kill i was trying to switch around the shipgirls and equipments, some of those that i remember:
-2cvl with 8 green plane
-kiso with opening ASW
-gangut at main fleet
-tama / ashigara / commander taste at escort fleet
-hatsuzuki with air radar
-searchlight on hatsuzuki / big searchlight on gotland
Try not to used akizuki class DD and Nelson:
(for 4 akizuki class DD, if used 1 at E2 and 1 at E3, there is only 2 remain and 3 ship lock at E4+E5)
However, i do feel easier pass on node J after i used akizuki class dd...
there is higher chance to finish main fleet of the enemies if nelson touch activate and aim at the correct target but i think support expedition should be helping too for final kill
For node J
-aim for AS and 2bb at main fleet make it easier to pass this node
(i was lucky that my final kill run is AD and pass node J

)
For gangut
-it seems easier to finish the boss if gangut at escort fleet and survive until night battle, however, it will be harder to pass node J with either 1BB or 1CVL/CV in main fleet
For CTF
-i do not CTF for second boss, not sure is it easier or not, it may easier however need 1 AO with fast speed...
For support expedition, i was use both support expedition for final kill, however, all have to retreat before reach boss node
and when i decide to not use both support, the run reach boss and finish the boss
I guess maybe i try some run on E4 casual while digest all the E4 information
