Flamu called it OP, not borderline OP. I mean it is the title of the review.
Belfast is blatantly OP and thanks to the WG policy of not nerfing premiums it's here to stay and pollute T7 forever. How this thing went through design and testing in this state is beyond my comprehension. It has no effective counter.
Lacks damage you say? Here you go. AFT captain, no DE, no CE, no fire flags. With those skills I have no doubt that I can push both the WR and damage even higher.
