No it doesnt work like no 2..

Any ships which enter E3 or E4 or E5 will be stamped.. Jsut Easy ignores Stamp

SO easy you can use any ships in E3-E5 (whole event atucally).

But ships which have done E3 (even in easy) can not do E4 normal. bec they are stamped.

So the cheapest way to do E6 hard (for hard medal) is

Hard Hard (first 2 doesnt matter, but you want to do hard if possible for best reward). Hard (no ship lock applied yet).. Easy (ship lock ignored.. so you can use those E3 ships. but you need to plan this bec of next one) Normal (ok those 12 ships you used in E4 easy can not be used here)

E6 Hard..

Best way to avoid ship lock completely is:

Hard Hard Hard Easy Easy Normal
