first : the how to dodge torps:
well this i kinda simple,
when you see an enemy ships with torp launchers never come to close and if he gets try to get close just get away from him and at same time shoot at him so he will or stop chasing you or slowing down.
when there is a torp wall you cant dodge, then try to run as fast as possible so the torps explode before they hit you , or try to get between the torps , and if none of those are possible you will have to take one torp(always try to eat the less torps you can , dont try to dodge if you really cant!)

and now teh how to use D-land guide
first, never use d-land with gunners lvl 45 your spread will be how to say it, HUGE.
so it will be very hard to use it , so wait untill they are 50+, then you will need good engineers so the unadvantage of being the slowest ca wont affect you to much, then always stay at max range , cause range is your only advantage,(try to avoid the most possible Yorks). DONT FORGET TO PUT PLANE! On D-land you should use the 3x11" N(NOT D OR ELSE YOU WILL LOSE THE RANGE ADVANATAGE!!!!!) and put 3 binds of light HE and 1 AP (against bc AND bb).

this is pretty much it untill now
