If you must scramble a battleship to prevent it from jumping then you just made battleships stupidly hard to tackle as well. Oh lolol, infinite point? How about I just teleport away for no reason whatsoever!
I have real trouble seeing a module like this ever making it onto TQ - it will always exist very far into the "useless" or "mandatory OP module" spectrum, never a balanced module. I wouldn't mind seeing a specific ship class get something like this (Blackops come to mind), but as a general purpose module? lolno. If carriers or dreads can fit it (which CCP would be retarded to allow) then they become an instant each choice for that first midslot on those ships.
