Get your butt in the IDEAL clan then
We are doing nothing but casual pew pew
1) I think the time to get the Missouri is already gone. But yeah, it is good. Biggest feature is of course its radar
2) If you get 5 signals it means you got nothing interesting. So far, by unlocking two containers per day since they have been introduced, i got 50,000 experience, 500 gold, 300 dragoon flags and 300 speed flags
3) It depends on the ship class you like to play in the first place. Bismarck with a full secondaries setup is indeed a keeper at t8. Overall, i think t8 is still where the fun factor is at the top and personally all trees are fun to play. Only advice is, for the UK CA, to skip to t6 or even t7.
