5*Hound, 4* Xanadu and Silencer, So good my 410k vs 361k loses every time

Gp means nothing, and yes, there are ways to beat ht + xb, but even with that, fleet arena is incredibly lame nowdays. With the tfp dodge (xb aes which is a guaranteed evade, and the capital ship also aes ehich is another ecade), everyone wins on offense.
This also means that nothing holds on defense, but not in terms of dropping 5-10 ranks overnight, but 30-50 ranks.

Cg clearly didnt test this (not surprised just stating tue obvious/usual).
