Right... must be intended for a Vet0 Pershing to shoot faster than a Vet3 Pershing. Logic. This community is lulzy.
oh then i missed the post the guy made. he made some math and result was pershings RoF is the same with combined arms with or without vet 3. so yes vet 3 is "useless" for the time combined arms is active.
atleast i dont have a fetish for little anime grills
