Insta locking Tornado in Highsec

Was just in a fleet fight as logi got alphad by enemy tornado fleet and they warped away as quick. you cant even lock up logi being primed in time. They lock in 0.5 seconds and you are gone. I think there should be some kind of lock speed limitation on bigger ships. I would like to have a chance to save people in a logi ship but having a battlecruiser able to insta lock is absurd . Cant even bubble them since highsec so cant catch them out
