Range and weight are close cousins: if you want one you need big engines, big tanks, a higher MTOW.
On specific planes trade range for capacity if the mission demands it: the 77W is the best example. It can fly 11-13k km but it’s still economical on a LHR-JFK half the length, packed to the brim with passengers and cargo.
The problem with the 778, as I see it, is similar to the 77L’s: if you don’t need the ultra long range the weight it carries around carries costs that are higher than a normal 777-200ER’s.
