As far as the Ambassador class If there are arguments that its too powerful for this tier or too old. Its not to old and it was If i remember correctly the only Enterprise that was designed as a warship because of the war with I cant remember the Klingons or the Romulans. Its meant to be OP.
The logic is shockingly bad here. I know it's a video game based on a TV show and inconsistencies about but this is a terrible justification.
I guess that's why I shouldn't engage in debates about this stuff.
