Yeah the update messed up my farming process too. Try using a really fast ship.

Well do one that takes around 30 seconds or less then add more guns then go up a level easy

Night battle Lvl 2 is great for quick farming. Unfortunately, it's only 1500 coins.

Do duel level 7 or duel level 6 or 5 and you should win quickly like me also save up money for a 46 cm gun it has long enough range to hit your enemy's quickly even at levels 9 and 10

On level 10, use a ship with at least 2 x 46cm guns on the bow. The battleships are really hard to hit as they come towards to you, so head for the aircraft carrier and take it out first - 3 direct hits should do it. Once its sinking, the two battleships will stop moving, so turn your guns on them

You can use MK 45 5 inch gun, it does not do a lot of damage but if you have maybe 3 or 4 it does not take that long couse of the accuracy. btw level 9 is a great farming duel with the MK 45.

Use about 10 mk 45s to kill duel 9

Just use around 2-3 mk45's and a couple of 46 mm guns . First use the mk45's to hit its boilers after you get in range ( so best for a ship that goes 60+ knoths my goes a 108 knoths ) after enough hits the this will slow down . And when it does the 46 mm guns will finish the job ( all in all for me it takes around 30 - 40 seconds to do this with 3 mk45's and 3 46 mm guns with three dive bomers in my custom made under deck hanger ( which scores an occasional hit . Hope this helps but don't take too long cause it tropedos may do some serious damage . ( it's the kind that only rare metals can buy ) so far I haven't got ton hit yet :). Sergent Ng out ( oh and please try to answer my question of what does ULR mean . Thanks.
