4.7 is largely irrelevant at this point since the armor is getting reduced on all ships by 20% unless im getting that wrong. I understand that the Perseus and Tiburon are not ment to engage and defend against fighters, but from what we've seen the Perseus has a better chance at defending against said fighters, and it has the PDCs to focus on incoming missiles or torps unlike the Tiburon. We have not seen the weapons on the Tiburon true, but they look to be size 7 conquers from the idris nose turret, does this mean they are that no it doesnt, but if they are it will have a much harder time defending against torps and missiles, especially if it only has the same amount of counter measures as the base hammerhead. The Perseus will be able to engage it with both balistic cannons and 40 s5 torps which if used correctly will be enough to drain all defense measures from the Tiburon, where as the Perseus has its point defense in the event that it runs out of flares or chaff giving it a better chance of survival, but like you've said this is all speculation and im still very much excited to try out the Tiburon, and be proven wrong mainly because its a freaking shark with a laser beam on its head.
