For me its rd 35 - gotta love single targetting, luckily picked xan co as my attack fleet who's only weaknesses were theifs and locusts which no on ebuilt and had immense amount of fun messy landing for huge xp gains all round. I even stopped defending at all in the last 3 weeks and just went all out every night 3 fleeting all the way!! Crashed 2/3rds of my fleet but then managed to rebuild and carry on attacking again. Finished 9th in uni for xp, which as it was my first full round in PA made me soooooo chuffed it inspired me to make more of an effort in the game from then on
Although it hasnt happened yet i beleive rd 37 will be an awesome round due to ST ofc and some intresting ally and game changes
